Staying off topic....
GPS systems in hi dollar bracket racing is what we hate hearing about.
Bill, my wife runs a 6.70 e.t powerglide top dragster and we definitely need a certain amount of wheel speed to get her on down the track briskly. Most of us look at the RPM to driveshaft differential at certain times into the run. If we suffer tire shake most of it occurs within the first 1.7 seconds of the run . . . the tire progressively (hopefully) hooks somewhere between 1.4 and 1.7 seconds into the run. As we have dropped below 7 second ET's tire shake has become a significant expensive challenge in terms of damaging parts and figuring out how to solve it. At anything above 7 seconds, in our car, it is a non issue -- you can just dead hook and go.
