One tenth reduction in 60ft equals.....?
I should clarify my previous statement. When I said the intervals stayed the same I meant the interval plus the slower 60 ft time. Example;
Run #1 1.68 60ft, 4.86 330,7.57 1/8, 9.91 1000, 11.91 final
Run #2 1.60 60ft, 4.79 330,7.50 1/8, 9.85 1000, 11.85 final.
These were back to back runs, only difference was traction. See how the difference between all the intervals is the same all the way down the track within a 100th or two. The time at the intervals is different because the slower 60 ft time but the time between the intervals stays more or less the same. Since my car is VERY consistant I see this all the time.
Based on my experience I have to respectfully disagree with your last statement if the 60ft time is slower only because of traction. If the cars are normally equal and the one car has a .10 60ft time reduction solely because of traction he would have to run .10 faster to catch him.
Interesting subject BTW. Would like to see other examples to see if my car is just a fluke.

The interval differences are pretty much set in stone. I have been doing this a long time & have several programs I keep records with. The 60' changes more than any interval on a full pass. When testing we usually shut off at 1000' & throw the interval on to get a 1/4 ET. Checking intervals is also a tool to find problems before damage happens. Again, it only works with the same car, engine, combination. I would bet people don't realize how consistant their intervals are. I was.

So do you agree or disagree based on real world experience that traction only 60 ft time differences are a 1:1 ratio for final ET?
