Interesting idea, but these distributions only matter if you plan to play (a) ALL of the games on a system, or (b) a COMPLETELY RANDOM SAMPLE of games on a system.
If you plan to choose the games you play with some eye toward professional reviews, personal recommendations, etc. (rather than at random), then the ratio of good to bad games doesn't matter AT ALL... as long as there are enough good games on the system (in terms of absolute number, not ratio) to keep you busy.
