The percentages are only for chances of winning. The remaining percentages are ties.
So a 7,3, or A - counterfeits the kickers in the first hand, A T,J,Q,K or A counterfeits the kickers in the second hand, and in the third hand the players kickers are already counterfeited.
They are all correct I believe. If its the percentages your worried about the chances of a tie are not included. I would be nice if they put the tie percentage up.
