Thats pretty much apples to apples

Thanks Dean!!

I think the trap has to do with exact speed vs speed in a range or something like that. I think track measures finish line speed vs draggy.

But like I said, Im not educated here.
Yeah, trap speed is the final speed as you cross the 1/4 mile mark—not your top speed—at least, that's how I've always understood it. Presumably, Dragy measures the same based upon its calculation of the distance and the speed at that point.

Is that what you're saying; not sure I'm following you?

// edit: trap speed I just learned/refreshed my memory is an average of the last 66 feet of the track... thanks to OnFire below for the real info.
