What is "You must have a timeout ratio lower than 10% to play in this tournament." ??

I don't know how else to explain it..

 I have greater problems.

It means that you must not timeout more than 10% of your games. 

If you completed 20 games and timed out in 3, your timeout ratio would be (3 / 20) * 100% or 15%. You would not be allowed to play. You are too likely to drop out and muck up the tourney or match for everyone else.

my's timed out or timed out of my oponnent's?

your time outs

ok, ty at all :)
