So, i was looking at my darkrai to decide what to try to roll for its last subability. I was kind of chill about it because I have been hearing that for its last subability either HB HSS or STM are quite balanced between each other and that it doesn't matter that much what you roll between the three. But I was comparing in Raenox and found out a great difference between HB and HHS or STM.

I later checked in the game and math doesn't quite add up to me unless I am missing something... It says HB allows team members to work 5% faster and HSS allows this pokemon to work 7% faster.

Can someone please explain to me why this difference if in theory HB should be slightly worse than HSS when making a pokemon faster?
