""do IVs matter" discussions often miss crucial part of equation: "how hard are they to obtain""

#PokemonGO: Lets do some quick set up first:** How hard is it to get 15 attack? **It is trivial."Bonus" pokemon (that come from Eggs, Raids and Lucky trades) have range of 10 - 15.https://ift.tt/2AriYew attempts (one month of raiding or 3 hour rush event) give player 99,6% chance of getting at least 1 15 attack pokemon with expected number of successes being 5.with 1 week of raiding (7 attempts) you get 72.1% chance of scoring 15 attack pokemon.Weather boosted pokemon have range of 4 - 15.https://ift.tt/2mWMHlU of getting 15 attack IV from catching 30 weather boosted pokemon is pretty decent, you can expect to get about 2.45,6% of getting 15 attack iv after catching 7 is pretty solid.Lets make table:TypeRange30 tries chance30 tries expected7 tries chance7 tries expected1 Tries chanceHatch/Raid/Quest/Lucky10-1599,6%572.1%116,7%T4 Friend trade5-1594,2%263,6%09,1%Weather boost4-1592,6%245,6%08,3%T3 Friend trade3-1590,9%242,9%07,7%T2 Friend trade2-1589,1%240,5%07,1%T1 Friend trade1-1587,3%238,3%06,7%Wild catch without bonus0-1583,6%136,4%06,3%This should demonstrate easily that pokemon with 15 attack is easily available.It takes 32 unberried catches to get enough candy to evolve 25+100 candy evolutions. Even if player is farming nest without any weather bonuses, he will very likely end up with one pokemon that is 15 attack and with 2 cnadidates if weather boost is active.For pokemon obtained from sources with IV bonus, it makes little sense to NOT discriminated based on IV.Big events like community days where players catch about 200 pokemon are even more interesting:https://ift.tt/2AzFAtt of getting 15 attacknd and expected amount of such pokemon being 16 in case of weather boost. And same 99,9% chance for getting one and expected 12 candidates without weather boost.** Desiring high levels **First, chance of getting 15 attack weather boosted pokemon at Level 35 is 1/360.That is ... pretty low. Even during big weather boosted event (200 catches) you have 42,6% of comming across one.So, there is obvious choice. However, if we widen criteria a bit (14,15 attack, Level 34,35) it is 89% chance and 2 expected successes.** TLDR **IVs matter simply because having perfect attack IV is easy to achieve and not that problematic to get on high level body.Especially for legendaries which only come in raids is having high IV both easy to get and easy to discriminate because all powerup candidates have same level. via /r/TheSilphRoad https://ift.tt/2v0WWdn
