I'm really curious if each event is calculated differently as i thought rating 3.0 was a fixed formula. ZywOo's stat in Mirage against Navi with a 30/7 KD, 162.4 ADR and 1 1vsX only landed him a 2.53, while comparing to the big difference in donk's performance against PV (in the game which they lost) in Rotterdam with 19/13 KD, 131.9 ADR and no 1vsX that landed him 2.05.

Although i'm aware of sayings that awp kills compared to rifle kills contributes less to increase in ratings. is the difference really this much?
