You are most likely correct. I was going off of what I was told ages ago, and my memory isn't perfectsohcd16y8 wrote:Traps speed is an average over the last 66 ft on all modern timing systems. I know some older tracks had different distances, but I have never heard of a timing system that averages your speed in the braking zone.

And it will never be. Speed is always a product of time and distance. So in some way you're always talking about an average speed. It will always be a trade-off between 'instantaneous' and accuracy. Shorter measuring distance also introduces an amount of inaccuracy.marshall.hagen wrote: Moral of the story is that your Trap Speed is not an 'instantaneous' speed.
