FWIW, the USCF classifies G/10 up to G/29 as Quick Chess. G/31 and above is classified as Standard Chess. Interestingly, G/30 can be rated under either. A player's Quick Chess rating is calculated independently of their Standard Chess rating. The USCF does not rate games played at a time control faster than G/10.
