I don't think it would make sense for a location based start on a drag strip. I'm not sure how I could set up an accurate location based end as well, they don't exactly allow a walk through on a drag strip.

If I set it for acceleration, say 0-100 mph at the dragstrip, and I cross the line at 110 mph (or 90 mph) would it still store the full run? Or will it just stop recording at 100 mph, or not record at 90 mph?

Is there a video or tutorial that shows how to use it for drag racing? I've never used your app before and don't know how everything works. I just remember seeing other requests for drag racing support and that it was always on your schedule of things to do.

Which of those apps directly supports 1/4 mile ET and trap speeds in drag racing? Or does it just plot a distance vs speed curve and I have to figure it out myself?

So which of your apps has the 1/4 mile ET and trap speed (drag racing) measuring feature? Can I use it at any dragstrip or is it only active at a pre-defined location based on GPS?

I have a garmin GLO which has a 10 Hz max refresh rate and have been trying other apps, but no one seems to have a good drag racing timer. Would it be possible to add this to Harrys Lap timer? In the past it seemed like Harry kept this on the back burner for several years. I'm hesitant to drop $500 ...
