Sucker Punch Kangaskhan Second hit on Lunala Shadow Shield

[FlorianvH]

When you try to calc for how much percent your Khan will do with sucker punch against Lunala you get 2 different damage values for the second hit, shouldn't the second hit always do the same amount of damage since the first one breaks Shadow Shield? First time im pointing something like this out on here hope i did it in the right place and such.
