Estimates based on 0-100 and 0-200 times. Car that does 6.2 and 24.8 will do ~15.7 quarter mile.
Accuracy of those 0-100 and 0-200 times can be disputed. Honestly, I can't tell you immediately where they come from (very old data) but I could find out if I did some digging.
I am sure it can do better than 6.2 and 24.8 0-100 and 0-200, it's just that I don't have the data. If I did, the estimated 1/4 would be calculated from the average acceleration data, which would include better results and the 1/4 calculated would be closer to reality.
In 95% of cases my estimates are within couple of tenths of a second from real tested 1/4 times. And in some cases the real test result can actually be less "real" and less representative than the calculated estimate (poor launch, or shifting, bad road surface etc).
