I want great track prep as well. Just saying it is a lot more involved that throwing down some rosin and spraying the track.
Predicting upcoming temperatures can make a difference what you "cut the glue" with (methanol or MEK). Different brands of traction compound offer TOTALLY different results on different tracks due to track texture or how much sun it gets. etc.

We struggle with our 700 HP nose heavy three-speed 3400-lb Cutlass in hot months but it can go 1.29 / 60s all day on good track but easily loses .03-.07 on greasy starting lines.

We just started using the MSD GRID and I think we found the cure. Using the launch retard we hooked every run on a very "green" track last weekend and only varied .009 in 60' over 6 runs. Slowed the car a bit but it was deadly consistent.
