How about changing the green/orange games completed indicator to something giving exact numbers:such as>Sept.games started=20--games finished=18.and if 95% rate is accomplished a 5 credit bonus is rewarded

More detail than we need. Green is good to go, yellow probably is too (I've been yellow several times, due to DCs). Orange is usually a serial quitter; if they last three holes, it's a good day.
Really all you need.
