Make some test laps with the throttle stop last night

[HR 9505]

I got a chance to finally test out the throttle stop last night for the first time. I made a flat out pass and went 6.48 at 105 mph, I then set the timers up as follows - on at .300 off at 1.70 shift at .5 and the car ran a 7.23. I go back and make another pass with the following - on at .300 off at 1.2 shift at .5 and ran a 7.14. I then did some crude math and came up with about a 5.5 to 1 ratio. I then moved my timer one to .2 and timer 2 to .5, shift at .4 and ran a 6.999. I left everything alone for the next pass to check consistancy but they sprayed the track on me and it picked up .06 in the 60' and ran a 6.94.

My question is.......am I ok with not being on the stop all that long? I have a heavy car (3500#) so shifting it on the stop really knocks the breath out of it.

By the way.....all these runs were set at 4500 rpm cruise

What are everyone's thoughts? I feel like I'm close but I'm new to this and want some opinions.

Thanks,
