for my person, such a display would influence me as following -

if I'd see somebody who challenges me having about 70%
of his games played as player1 I would simply DEMAND that,
in a first encounter he'd take player2, because I evidently couldn't
rely on the custom of granting a 2nd game with exchanged colours
- happened already.
I won't name the player though - may he remain happy ... :Þ ... ~*~
