"Theory: Potential Bug with IVs"

#PokemonGO: A number of users have already posted trends regarding the attack IV stat for certain pokemon. /u/TBNecksnapper and /u/justinleeewells have discovered that most wild-caught Eevees (not nests nor hatched) have attack IVs of ~14-15. See their posts here and here. I have actually noticed the same exact thing with my pokemon - Eevees and eeveelutions tend to have high attack IVs, making it much easier to find eevees with >80% IVs. (it's still possible to find a 15/0/0 eevee for only 33% IVs, however!)On the other end of the spectrum, /u/joffrey_crossbow posted this about bulbsaurs/charmander/squirtle caught in the wild having attack IVs with a bias for 0! After digging around some more, I found a 4 day old post by /u/newschoolboxer here that explains a theory regarding the biases in Attack IVs we've been noticing. His theory (with empirical evidence) states that Attack IVs for pokemon are incorrectly tied to their pokedex number! Thus, bulbasaur/charmander/squirtle tend to have 0 attack IVs, whereas magikarp, eevees, and dratini tend to have 15 attack IVs. This also means that pokemon like poliwag will almost never have attack IVs that are higher than 9.This theory only applies to wild-caught pokemon. It seems that pokemon from nests and hatched pokemon have their own IV biases that override this bug. We know that nest pokemon tend to have lower IVs and hatched pokemon tend to have higher IVs.However, with this bug, it implies that it will be impossible more difficult than 1/4000 to find perfect IV pokemon, unless it was hatched or it has a pokedex # of greater than 125 or so!tl;drUser newschoolboxer came up with this chart showing that attack IVs are tied to pokedex # of wild (non nest/non hatched) pokemon.I've been able to corroborate his theory with my pokemon, but let's try to get some more data on this!EDIT: Forgot to mention that pokemon you get at the start of the game (first bulbasaur, squirtle, charmander, or pikachu) seems to have set IVs at 10/10/10 (or at least have the same egg hatch IV bias towards the higher end). Therefore those are exempt from this theory too. via /r/TheSilphRoad http://ift.tt/2agcXiv
