If you hit 130 rpm, then you either have a typo in the gear, or you took an unbelievably inefficient line - my back-of-the-napkin calculated 130 rpm in a 49/13 to be about an 11.5.

i'd say that if you did a terrible line with undialed gear, then you can probably take off .5 seconds just via practice. Getting your timing, execution, and gear right. Doesn't have to take 3 months. Just takes a lot of flying 200s.
