Sure. Just play more games and don't time out in them, and your ratio will decrease with each game you finish. Also, the timeout ratio only looks at games during the previous 90 days.
timeout %

The new system where only the last 90 days are counted means, for most people, there is too short a time to lower the timeout % by completing non-timeout games. The timeout % may even increase without more timeouts being incurred. Non-timeout games that become older than 90 days have to be replaced and even more non-timeout games have to be added to lower the timeout %.
In practice, the timeouts have to fall out of the calculation in 90 days for the timeout % to decrease.
The original poster can lower his timeout ratio since he has zero non-timeout games to replace, only non-timeout games to add. He is unlikely still to reach the magic 10% timeout ratio until some of the timeouts fall out of the calculation.

That's a safe bet, since 1 of his 3 timeouts falls out only 10 days from now. The other 2 fall out within another 3 weeks after that.

where or how do i find out what is my time out ratio?
