Well... I see a lot of debate here and it's very good to get all the opinions together. I only wanna say one quick thing. For me it's not possible to continue playing with a 10 games limit. I have an high average of game duration and I'm no kid to spend all my time playing for ranking. I like this project with the ranking system but no more play for me because now it's not fun.
I have an average score of 9.78, a total of 60 games(!) and my games for the last week are now 11. Tomorrow I'll get the malus. I played almost 8 to 9 hours this week! I'm not spending three hours playing tomorrow so I can keep the average without the malus.
The all-inners, the guys with more than 10 hours per week for playing online poker and the addicted are the ones who can play with this malus system, not me!
Good luck for everyone.
