how is this possible?


not unusual at all...look at the multiple i cant improve threads and note how much blitz and bullet they play...lots of people enjoy blitz more☺
The same happens with my rating. I have played only one daily game (which I lost), but many thousands of blitz and some thousands of bullet.
In fact I had no intention to start a daily game, I started it accidentally accepting a challenge.

This actually seems pretty common... people who love to play live games, but can't care about games that go on for more than a few days.. they just lose interest?

I have a question, if I improve my slow games will I automatically improve my rapid games? Recently I almost hit 1500 rating in slow games, does it indicate that I can also achieve 1500 rating in rapid games?
