Rising in the Rankings

[TheGreatErenan]

Right, which is why I said you would have to focus on players who had played many many matches. However, intuitively it seems that you'd have to play quite a large number of matches before you could reasonably expect to see a rough evenness among the numbers of times you played on each map. But what you said is true. If a player has played hundreds of P1 matches and absolutely none of them are on a particular map, it seems very likely that they cancelled P1 matches on that map.

In any case, admittedly without having put much thought into it, I am in favor of implementing a hidden ranking penalty when quitting a P1 match prior to being assigned an opponent, and this would make all of the above data analysis unnecessary, since people would presumably stop doing it.

Alternatively, I would be happy with the "can't make a move until both players are in the game" solution as well, but I understand that there are significant downsides to this.
