If i am not senile yet, personal trainer trains all attributes as of equal rate. Now once i hit by +4%, 3 of the skills are staying same, 3 of them increase at double rate is +8% to balance overall quality.
It's shown simple in the picture. Regular personal trainer prices are not correct. Another problem, when i tap over PRICE header, Players are the last column in the range is sorted by prices, but after that i touch first player on the list, it opens wrong player's profile ( actually players are still on the list how it's sorted by default)
