1/8 mile time multiplied by 1.555

Now way there is a perfect formula. From experience 4.60 = 7.33 5.65 = 8.90 6.10 = 9.50 and 6.90 = 10.90

I have seen some et predictors that had run completion, but that was if you lifted at the 1000 ft

I like to use 1.57 but like everything else one size doesn't fit all.

► 9.985 / 6.315 = 1.58116
► 10.10 / 6.394 = 1.57961
► 10.103 / 6.421 = 1.57343
► 10.154 / 6.444 = 1.57573
