First off, I hate it. I hate that the score was like that. It bothers me. I don't like to see players or teams embarrassed. It's dumb.
With that said, your numbers are wrong. Here is the breakdown:
Minutes played:
0-10 minutes played - 2 players (4, 6 minutes)
11-15 minutes played - 5 players (11, 12, 13, 15, 15)
16-20 minutes played - 3 players (17, 17, 20)
21-25 minutes played - 3 players (22, 23, 25)
The top 7 players played 139 minutes which is 69.5%
The next 6 players played 61 minutes which is 31.5%
Are those numbers great, no, but nowhere near as bad as what you posted.
