ThunderGr: I find it also too cumbersome to check each discipline, especially as it is a moving target - I might be in today, and out tomorrow.
In addition, and I mentioned that before, the top 10% are mostly people that do not play anymore, so effectively this limits it to 2 or 3 % of active players. Which is to small a pool I think.

And finally, I am simply not good enough to make it into the top 10% of most games, so I stopped checking.
