Based on my experience with my cars
[been running there since 1983}: when I was running 11`s/12`s Quaker was about 10th slower,as I got quicker MPH was still down at Quaker IE.you are climbing a hill the last 300 ft. ,but the E.T. gap narrowed.

Now on my traction limited boosted street car Norwalk is quicker and faster 1.5 ET./2mph.

I believe some of the variation in results is where your car makes its move or is lacking in perfection.
