Rob changed his answer after . It was a little tricky for him .


As for the proper definition of the top 10 % of all hands .
Since there are 1326 different hand combinations , then you should select the top 1326*0.1 = 132.6 hands but you must choose the top 132 hands . The 133rd hand is not included in the top 10 % and so you can do slightly better by folding it .
