>>29042914Yes, he has 50% of getting 31iv in SpA, but that stops him from getting hp grass.
I made some rough calcs. He can get 30 SpA IV at most.
As it turns out, the hp calculation uses the last bit of every iv and in inverse order, creates a new calculation
So, in the middle column, every digit represents, spd, spa, spe, def, atk, hp in that order
So being that the second digit is always 0, hp grass can't have a 31 sp atk iv.
So his absolute best case scenario
1/2 to not have SpA set to 30
1/25 to have Modest
1/32 to have SpA randomly set to 30
That alone gives you worst odds than Shiny Charm Random Encounter, and that's not counting that the 31s have to hit the right stats.
tl;dr killing a gastrodon is not fucking worthy.
