I got bored and autistically broke down my favourite Pokemon by origin Gen and type, then did it again but weighted for the total number of Pokemon of each Gen/Type.
There were probably some inaccuracies in my numbers but the results look like pretty much what I'd expect
>Gens 3 and 7 pretty high, with 4 quite low
>Flying/Ghost very high
Gen 8 and Fighting type being so high are the only things that suprised me

Any other anons have anything autistic to share?
