Also what do you mean with breaking the beams?
OK Dirka I'll try to help. If you took two pieces of string ran them parallel to each other say a 1/2 inch high and a 1/2 inch apart to simulate two beams of light. Now if you took a dime and stand it on edge it would just touch both pieces of string or both beams of light. Now if you took a quarter and did the same it would touch both strings or beams of light longer. Hence short tire vs taller tire. Taller tire stays in the beams longer fools the timing system a little where as you are moving a little and it can't tell till you move enough to clear the back string or light as it be.
ET is elapsed time or how long it takes to run the 1/8th or 1/4 mile. Sorry so long . Hope this helps.
