If you have 2-3 cars running a combination that is capable of easily running 1.4 under, and and 25-30 cars running a combination that will run 1.2 under, the 25-30 cars will get hit first, and more often, because one slow car out of 2-3 is a bigger percentage and affects the average more than 5-6 slow cars in the 25-30 car group. If you move to the 1/8 mile index, you'll hit automatic cars harder because the stick cars ET better further down track than the automatic cars. You'd also have to look at the fact that quite possibly the cars running more than 1.4 under gain more in the second half than the cars running 1.2 under or less, so the difference at the 1/8 mile may not be great enough to hit the faster cars first and/or harder. I'd have to look harder at a lot more data to see if trying the trigger at the 1/8 mile mark could work. If you take away weight as a way to kill off ET, a smart racer will just kill timing and/or short shift to kill off ET, or do something else. We used to do it all the time running Super Comp instead of adding weight or using a throttle stop, because weight hurt the reaction time. Shift 1000RPM (or more) sooner for one or two shifts and you slow down. How are you going to stop that? Kill 20 degrees of timing and you slow down (all you have to do is leave the start timing retard on). How do you stop that? There are a bunch of ways to kill ET, too many for them to police. We can run the car 30 degrees hotter and kill ET. We can put thick oil in it, and add an extra quart and kill ET. Weight is just easy.
