At the beginning of Generation 8, there was an update to tiering for lower tiers where Smogon adjusted the usage threshold from 3.41% to 4.52%. Reasons cited for the policy included decreasing how disruptive tier shifts were to lower tiers, counteracting ripple effects in lower tiers, and making drops more frequent than rises. I think this was a change in the right direction, but I don't think it was enough of a change: most tiers still end seeing more losses than gains. At the end of Generation 8, there was another tiering policy, and it froze rises altogether after citing instability from the effects of rises. I'm going to explain why tiers were and are still unstable, and then I will propose a change.
Before the January 2025 tier shifts, I made a post in the usage stats discussion thread, and I've condensed all the information from it into this one so it isn't necessary to read the old post. My observation was Pokemon in lower tiers are rising faster than they're replaced by new drops, which continuously and progressively destabilizes lower tiers. This contradicts the intention of the "Tiering for Generation 8" policy of facilitating more rises than drops, as the 4.52% usage threshold still isn't dropping more Pokemon into lower tiers than it's rising up to higher tiers.
As current gen usage-based higher tier metagames develop, they tend to pull up Pokemon from lower tiers. Pokemon may become better as they metagame develops, they secure new niches, or they just gain consistent usage. One example of an impactful rise is Zapdos's movement from UU to OU in the October 2024 tier shift. When a tier loses a staple option, it creates a vacuum, and that vacuum pulls up Pokemon from tiers below. When Pokemon from those lower tier fill a vacuum, they create bigger vacuums in the tiers they leave behind. This effect creates disruptive tier shifts like the following:
How severe is the tiering vacuum?
I've compiled all of the DLC2 SV tier shifts and tiering actions so no one else has to go through the trouble of checking all of them. However, I've still linked all of them in case anyone wants to check my work or point out something I missed. I'm including Pokemon tiering actions in this because they still remove options from lower tiers.

OU made 4 new Pokemon bans.

UU lost a net total of 9 Pokemon to rises and bans. 3 of its gains didn't stick and fell further.

RU lost a net total of 14 Pokemon to rises and bans. 6 of its gains didn't stick and fell to lower tiers.

NU lost a net total of 21 Pokemon to rises and bans. 2 of its gains didn't stick and fell to lower tiers.

PU lost a net total of 18 Pokemon to rises and bans. 3 of its gains didn't stick, falling to lower tiers.

ZU lost a net total of 12 Pokemon to rises and bans. 4 of its gains didn't stick and fell out of the tier.
The Pokemon that fail to stick around make the tiering vacuum more powerful than I'm describing with the net gains/losses. Torkoal having no role in NU means that it's basically an empty drop that doesn't do anything about the tiering vacuum.
Lower tiers lose more Pokemon than they gain, at an average net loss of about 15 Pokemon at this point. Tiers are approximately 37 Pokemon in total, so nearly half of each tier is gone without replacement. This caused the severe tier shifts in July, October, and January when some tiers suffered major losses. Pokemon aren't just rising to higher tiers because they're emerging into new roles, they're having to replace what's been lost. I can pretty securely predict that the upcoming April tier shifts are going to be pretty destabilizing too, which will ripple into later tier shifts. Lower tiers are cannibalizing each other just by developing. By the end of SS, most lower tiers saw a net loss of 23 Pokemon even without rises for the last full tier shifts. SV is continuing on for what looks like an extra year compared to SS, so the tiering vacuum in SV is going to be even more severe in SV than SS.
Lower tiers losing pieces drives tiering action, which makes the vacuum stronger. Previously borderline or not-broken elements tend to become banworthy when the things holding them back are sucked up into higher tiers. Bans also create vacuums, which accelerates the process of pulling up more Pokemon from lower tiers. The lowest usage-based tiers, NU, PU, and ZU, are most strongly affected by the progressive tiering vacuum. This is why I've included tiering actions in this discussion, as they contribute to the effect we saw in SS and continue to see in SV.
Lower tier instability creates stress on lower tier communities. Lower tier councils have to be even more proactive and engaged, metagame resource contributors have to work harder, and tournaments become more volatile. Overall, this situation creates a lot of burnout across the types users affected by it.
My proposal: raise the threshold for rises and keep the same threshold for drops, making ~6.78% the new threshold for a lower tier Pokemon to move to a higher tier. 4.52% usage reflects a 50% chance that a player will see a Pokemon in a series of 15 games on the competitive section of the ladder. 6.78% reflects roughly that same chance in a series of 10 games, just as 3.41% usage reflected a 50% chance a player would see a Pokemon in a series of 20 games.
Raising the rise threshold above the drop threshold would reduce the number and frequency of rises from lower tiers.
There are Pokemon that hover around the 4.52% threshold, such as Blissey and Meowscarada in OU. Blissey still moved back to OU instead moving from UU to RU in January 2025's tier shifts, and now Blissey is on the verge of dropping to UU again. Blissey even made its way down to NU earlier in SV, but it keeps rubber-banding to OU just because of the small fluctuations around the 4.52% threshold used for drops and rises. A policy of detaching the rise threshold from the drop threshold would let lower tiers hold onto these types of Pokemon instead of dealing with constant shifts.
As proof, here's what would have changed for SV with this decoupling in place from July 2024, the first 3-month average tier shifts, onwards.
This wouldn't stop some shifts, just delay them. That said, it can be hard to say which changes might be "legitimate": a Pokemon appearing in the teambuilder biases players to use it more, even on the competitive end of the ladder. Since ladder is not completely detached from metagame trends, we'd probably still see changes like Iron Crown moving to OU and Decidueye moving to NU. Delayed and reduced rises would make it easier for lower tiers to anticipate how dramatically things would change in an upcoming tier shift.
Unlike the rise-freezing policy of SS, this policy wouldn't stop rises altogether. Tier shifts like RU-UU Cobalion, NU-RU Slowbro, PU-NU Bronzong, and NFE-PU Rhydon still would have happened when they did. I've put together a compilation of rises that still would have happened "on-time" like with how they did in the current system.
My goal with this discussion is to increase awareness that rises are still more frequent than drops in the current tiering system. My perspective is we should do something about this effect driving the instability that usage-based SV lower tiers have been dealing with. I think SV would be better off than SS by getting earlier jump on this rather than having to potentially freeze rises and conduct several suspect tests.
Tl;dr:
1. Rises, tiering action, and useless drops still outnumber useful drops for usage-based lower tiers.
2. Lower tiers are experiencing instability, which is bad, and the lowest ones have it the worst.
3. Making rises and drops separate could help lower tiers.
I'd really appreciate hearing others' thoughts on this pattern, my proposal, and experiences with the different sides of the issue, especially from those who drive lower tier development.

The Pokemon that fail to stick around make the tiering vacuum more powerful than I'm describing with the net gains/losses. Torkoal having no role in NU means that it's basically an empty drop that doesn't do anything about the tiering vacuum.
Lower tiers lose more Pokemon than they gain, at an average net loss of about 15 Pokemon at this point. Tiers are approximately 37 Pokemon in total, so nearly half of each tier is gone without replacement. This caused the severe tier shifts in July, October, and January when some tiers suffered major losses. Pokemon aren't just rising to higher tiers because they're emerging into new roles, they're having to replace what's been lost. I can pretty securely predict that the upcoming April tier shifts are going to be pretty destabilizing too, which will ripple into later tier shifts. Lower tiers are cannibalizing each other just by developing. By the end of SS, most lower tiers saw a net loss of 23 Pokemon even without rises for the last full tier shifts. SV is continuing on for what looks like an extra year compared to SS, so the tiering vacuum in SV is going to be even more severe in SV than SS.
Lower tiers losing pieces drives tiering action, which makes the vacuum stronger. Previously borderline or not-broken elements tend to become banworthy when the things holding them back are sucked up into higher tiers. Bans also create vacuums, which accelerates the process of pulling up more Pokemon from lower tiers. The lowest usage-based tiers, NU, PU, and ZU, are most strongly affected by the progressive tiering vacuum. This is why I've included tiering actions in this discussion, as they contribute to the effect we saw in SS and continue to see in SV.
Lower tier instability creates stress on lower tier communities. Lower tier councils have to be even more proactive and engaged, metagame resource contributors have to work harder, and tournaments become more volatile. Overall, this situation creates a lot of burnout across the types users affected by it.
My proposal: raise the threshold for rises and keep the same threshold for drops, making ~6.78% the new threshold for a lower tier Pokemon to move to a higher tier. 4.52% usage reflects a 50% chance that a player will see a Pokemon in a series of 15 games on the competitive section of the ladder. 6.78% reflects roughly that same chance in a series of 10 games, just as 3.41% usage reflected a 50% chance a player would see a Pokemon in a series of 20 games.
Raising the rise threshold above the drop threshold would reduce the number and frequency of rises from lower tiers.
There are Pokemon that hover around the 4.52% threshold, such as Blissey and Meowscarada in OU. Blissey still moved back to OU instead moving from UU to RU in January 2025's tier shifts, and now Blissey is on the verge of dropping to UU again. Blissey even made its way down to NU earlier in SV, but it keeps rubber-banding to OU just because of the small fluctuations around the 4.52% threshold used for drops and rises. A policy of detaching the rise threshold from the drop threshold would let lower tiers hold onto these types of Pokemon instead of dealing with constant shifts.
As proof, here's what would have changed for SV with this decoupling in place from July 2024, the first 3-month average tier shifts, onwards.

Unlike the rise-freezing policy of SS, this policy wouldn't stop rises altogether. Tier shifts like RU-UU Cobalion, NU-RU Slowbro, PU-NU Bronzong, and NFE-PU Rhydon still would have happened when they did. I've put together a compilation of rises that still would have happened "on-time" like with how they did in the current system.
Here are all the rises that still would have happened "on-time" with how they did in the current system.
Even though I only applied this to the 3-month average DLC2 era of SV, it would also stabilize the pre-DLC2 period. Lower tier councils would have more breathing room during the most volatile period of the generation, and playerbases would not have to deal with as much chaos.

My goal with this discussion is to increase awareness that rises are still more frequent than drops in the current tiering system. My perspective is we should do something about this effect driving the instability that usage-based SV lower tiers have been dealing with. I think SV would be better off than SS by getting earlier jump on this rather than having to potentially freeze rises and conduct several suspect tests.
Tl;dr:
1. Rises, tiering action, and useless drops still outnumber useful drops for usage-based lower tiers.
2. Lower tiers are experiencing instability, which is bad, and the lowest ones have it the worst.
3. Making rises and drops separate could help lower tiers.
I'd really appreciate hearing others' thoughts on this pattern, my proposal, and experiences with the different sides of the issue, especially from those who drive lower tier development.
