Everything on the track is determined by time. Every thing that happens is supposed to happen at the exact same time every pass. So why not the shift too? I'm talking bracket/.90 racing with a 2 speed.

In .90 racing, every thing after the stop comes off should be the same every pass. So...make sure the car dead hooks every time, have a powerplant with a flat torque curve and maybe even short shift it a bit, at the exact same time every pass. The big MPH .90 cars drop it into high gear just after going on the stop so it's a simple high gear charge when the stop comes off..

When I was .90 racing with a 3 speed, I would go to second a few hun after the hit, run the stop in second, and then shift to high by RPM. Sounds screwy but it worked pretty well. Like anything, you have to test, make laps and keep track of data.

If you spin? If you spin, you're done anyway unless the other guy screws up too. Make the car not spin is my advice.
