So I have been making “good” use of my free time in class and spreadsheeting out the effectiveness of all 816 offensive combinations against all 171 defensive ones, then sorted by SE% and Neutral %.
Unsurprising, the top hits were Normal/x/x, Ghost/x/x and Ghost/Dark/x, and because their inclusion completely messes up any way of drawing a meaningful conclusion, I tentatively filtered out Normal and Ghost from the list. Doesn't mean I recommend against them, I'm just doing so to be able to better draw trends
1. Here's the top hits when allowing type combinations that hit <4.5% of all type combinations for resisted
2. And here's the top hits for type combinations with perfect neutral coverage, Normal/x/x and Ghost/Dark/x included.
I know this is an overextrapolation because not all type combinations are equally represented in competitive tiers, but I found some interesting things that may come in handy for further discussion.
1. Unsurprisingly, Electric, Dark (and Ghost) and Dragon is showing up a lot on the top neutral hits, very expected because those are the types I think of when I think "neutral" typing.
2. I previously said that Fire/Poison/Dragon is a mostly neutral typing based on a hunch, but now I have the data to support it. Across all types that hit everything at least neutrally, it has the 8th highest neutral %, and the 3rd if we exclude Normal/x/x and Ghost/Dark/x.
3. Despite being one of the most neutral type combinations out there, it still hits 42% of all type combinations for SE, which is much higher than I anticipated. For reference, Electric/Ice hits 36.3% of all combinations for SE, but in practice it feels like it's getting to hit SE more often. I think the lesson here is that SE% and Neutral% on these tables is only for the sake of depiction, and may not full represent how it plays out in an actual tier. Certain types are more viable in certain tiers than others.
I'm planning to fine tune the data to only look at typings well represented in the VR, but I'm presenting my preliminary data in case I didn't finish looking at it. (done)
==========
Appendix:
1. Top hits if Dark is excluded instead, to avoid Ghost/Dark/x
2. Top hits if everything is allowed
====================
Important addendum
Glad I decided to look at this sheet with VR as denominator, because I'm surprised at the difference
1. <4.5% resisted; Normal, Ghost excluded
2. <4.5% resisted; Normal, Dark excluded
3. unresisted; full data
4. unresisted; Normal/x/x, Ghost/Dark/x excluded
My apologies if my post turns out extremely image-heavy, and if so I can just share the imgur url instead.
