crazy i may be, but i fell like your chess com rating changes too much after a win/loss. for example your bullet rating can change from 1200 to 1350 and then 1200 in 2 days. i think the K factor for time controls should be like this:
bullet:6
blitz:8
rapid:10
Fell free to disagree with me.
The site uses the Glicko rating system, though may change some of the associated variables. The determination of rating change is going to come down to each player's RD values.
