I would look at two things..

First I'm assuming that you are running 10.90 (with 2 secs in the stop)..

I would try shifting on time, like at .3, and see if that makes it any better...if you play back the tach, are you gaining alot of RPM before the stop comes off ? If so this could make you're 60's inconsistant...if you cant shift on time try lowering your stop RPM to 3900-4000, this can help with the RPM gain...

Secondly, you may be spinnning at the hit, are your reaction times varying with the 60 ? If you are spinning lowering your starting line RPM , along with changing your first number to .05 can help....
