Complete lots of games, don't time out on any of them. Wait for the games you have timed out on to pass 90 days (it may actually get worse if non-timeout games go over 90 days and your timed out ones are more recent). There's no other way.

As a premium member you have auto-timeout protection and you have vacation available "Vacation: 1 month 29 days" so you have to boycott No Vacation tournaments.

To add to the comment by The_Hess. It is almost impossible to lower the time out ratio before the 90 day expiry. You just keep the timeout ratio at the same amount by completing non-timeout games to replace those that expire.

Is timeout ratio calculated based on rated games or on all games?

I have not timeouted any game nor have I lost (recently) any game on time and still my timeout percentage is increasing!! What's the mistery? How the timeout ratio is calculated? Maybe if I win a game on time (which is not at all my fold) it's added to timeout ratio?! I consider myself a decent matematician, but this is something I can not understand!

As indicated in post #2. "it may actually get worse if non-timeout games go over 90 days and your timed out ones are more recent"

Your non-timeout games expire as well, so if they are dropped from the calculation while recent timeouts are less than 90 days old the timeout ratio can increase. This is why players usually have to wait 90 days, without timing out again, for a decrease in timeout ratio.

It makes sense if you have timeouted  games in the last 90 days, but it doesn't if you don't have !!

Play more games and DON"T time out any more.

Well, 90 days ago was December 14th, 2010. You have at least one timeout in that time frame.

It seems ny english fails... I do not have any timeout in the last 90 days !!

And unless I miscounted, you have 5 and only 29 games over that period; that is a 17% timeout ratio ... which means I may have missed one, since you show as 21% timeout.

No, your english doesn't fail. What I linked to was the 1st timeout that falls into the last 90 days. I found 4 others ... I'll post them or message them to you if you like.

I apologize! Because I have not the full statistics of my games (as a free member), and the games I lost on time were long ago, I assumed there was some mistake in my timeout percentage. Moreover, I have not used my vacation time (which I confused with this) since last sommer. Thank you Martin!
