I can see how that might help..but I don't see it being accurate enough to measure consistently in the smaller increments of time needed. ( .10 or less)
Then you have the issue of hauling all that stuff ( measuring wheel, cones, a rake to groom the area with..) out to the drag area on a drag bike with an override..
I wish I could rely on my butt dyno..but it's not calibrated very well.
