My understanding on the way it works ... the game totals the distribution number of you current lineup and then calculates each individual player as a percentage of the total. Say you gave your 5 players the ratings of: pg-2,sg-3,sf-4,pf-5,& c-6. The total would be 20 so your pg would be 10% of the time, sg 15%, etc. Of course your ratios change as players move in and out of the lineup.
