62 mph = 99.78 kph =100 kmph nice round metric number (27.78 m/s)
39 mph = 62.75 kph = not a round number or 17.36 m/s also not a nice number

Given the computer controls to wing and the computer has wheel sensor inputs? might relate to x many revolutions of the wheel in a time period or a revolution of the wheel in xxx milliseconds or less?

If the computer controls the wing of course it is programmable just not by the user.

If the wing size is adequate for the SRT-6 then it could be set up to rise earlier, or the time it rises could be variable perhaps depending of throttle position - pops up at 20 mph on full throttle.
