ET prediction with weather change ?

[Mark Yacavone]

I would say that Professor Vic is on the money here. I never had good luck trying to save run data from track to track, especially around here , or with using some kind of sliding scale. I just correct from the last previous run , if it did everything right.
For instance, going off Friday am , Saturday, 1st round showed a 14.617 corrected slightly. Car ran a .615.
Unfortunately , we were dialed a .62.
