You should gain ET, run quicker, by some .0001s, not loose it due to the clocks stopping sooner off of the stripe taker, correct work
If your traveling at 140 MPH when you multiplied 140 MPH by 5280=739200 which is the feet per hour, correct work If you multiply that by 12 inches for inches per hour you get 8870400 inches per hour which = inches per minute when you divide that by 12=147840 inches per minute which divided by 60 again to get the feet per second=2464 inches per second which also = 205.33 Ft. per second, correct work grin
If you took a 18 inch extension for the stripe taker from the front edge of the tires it should be the same as dividing 2464 by 100 to get the inches per one hundred of a second, correct confused 2464 divided by 100 =24.64 inches per .01 ET so the gain should be less than .01, correct work scope
I'm not a math guru or drag racing geek so those more in the know on this please chip in if I have part of this math incorrect please so I can learn the proper way to figure things like this out bow devil up
