Oh I haven't seen that, some concreate stuff, let's look at your games, I got this result (read from right to left):
And... If you remove your 3 and 4 players games, you got:
- 126 victories and 160 defeat (44% of victories)
- 27 series of one defeat then two victories
- 3 series of one defeat then five victories
- 24 series of one defeat then two, three or four victories (then one defeat)
You was expected to get about 2.3 series of one defeat then five victories. You got 3.
