All 3 of mine by hand was identical. I was good on the start every time. But I think I was slow on the stop. At least it's in the same ball park. When I raced moparornocar. He's stock tires but had a couple hundred more lbs payload than I did. He would beat me to 30 but then I would walk him like nothing. There's a lot of variables.I wasn't watching the Honda speedo. I was using the app to get actual speed. I did this test with stock tires.
Another thing I did was use the phone in the phone mount so it did not move. I set the parameters from 1 mile an hour to 40 mile an hour. That way the timer didn't start till it hits 2 mph.
I'm sure the connection with satellite will vary depending on what area you are in. That could have an effect on the GPS accuracy.
When I say I took an average of three runs, actually all three runs were identical using the timer.
