The breloom analysis is fine imo. The sash set is just an extension of the technician set really and idt it is that good nowadays anyway 'cause weak. PHeal is there 'cause it's just a kinda old set that never got taken down but it's not that big a deal as it's not like it's inviable or anything (unlike Specs Kyu-B which is just a worse Specs Kyu). Scarf Breloom is a trashy gimmick at best and is defo not worth listing as a full set.
I think maybe Force Palm could get a mention in moves for the technician set and may even be worth slashing instead of Rock Tomb as it's rlly nice in general for a more powerful STAB to use vs. slower 'mons that don't care about Bullet Seed and for it's paralysis rate whereas I can't remember the last time I saw a Rock Tomb Breloom off of low ladder and it just isn't as effective as it was in the past. That's the only thing I think could be changed on there and even then it's not a big deal if it isn't.
I don't want to offend you, and if I'm being compleately ignorant with this claim then I apologize, but I believe your underestimating Breloom's potential. For one thing, the sash set is almost compleately different to the LO set, as it commonly runs moves like Focus Punch instead of the standard Breloom moveset. Besides, recently the sash set has become just as, if not more popular than the LO set as it virtually gives you a free Spore against your opponent.
And Poison Heal is unviable, as there is almost no advantage for using it over the LO or Sash set. Most of the time, Breloom dies to one good hit anyway, so it doesn't extend Breloom's lifespan at all. All it does is make Breloom less powerful by taking away it's technician boost. There's a reason it is never used on the high ladder: because it destroys Breloom's potential.
And the scarfed set isn't as "gimmiky" as you might think. With a scarf, Breloom hits 393 speed, allowing it to outspeed all it's normal checks and put them to sleep with Spore. A fast, 100% accurate sleep move is something no other pokemon has acess to but scarfed Breloom. I feel like at the very least, it deserves a mention.
Again, sorry if I was kind of rude, but I feel like Breloom is one of the most underrated pokemon in the game, and the analysis is the root cause of that. It undermines the effectiveness of the sash set, which is one of the most popular Breloom movesets today. Overall, I feel as though it doesn't give a proper analysis of Breloom's potential and best sets, and needs to be revamped
