If you don't have enough hp to get the car past the 60ft timers with the setting you have in the stop now you can raise the stop rpm to consistantly get past the 60ft timers. If your car doesn't wheel stand too much, you can just put the stop on later (dragster's don't care door cars do) if the stop comes off after the 60ft timers every time your 60ft will tell you if you spin or not. If you have enough hp to get past the 60ft timers in this heat you should have no problem when the weather gets better. Hope this helps I have run door cars and dragsters on the stop and have a little experience with throttle stops.
