>>14026024You're supposed to get 1 perfect IV for every pokemon in your 20th to 29th chain, 2 perfect IVs for every pokemon in your 30th to 39th chain, and 3 perfect IVs for every pokemon in your 40th chain onwards.
Instead, because of shittily wrriten code, you get 1 perfect IV from your 20th chain only, 2 from your 30th chain only, and 3 from your 40th chain only.
