Chuck, this may have already been covered, but...

When calculating a player rating, the most recent 25% are doubled.
So lets say I have 40 rounds. The most recent 10 will count twice.
Say all of my tournaments are 4 rounds each. So that means the most recent 2 tournaments will be doubled along with 2 rounds from the one before that. Do you double rounds 3 and 4 from that other tournament or do you use rounds 1 and 2?

Thanks
