So, if I choose miles, I should put in 0.00984848? That's how much of a mile my track is.
I assumed that it was in feet if I chose mile, so we put in 50. At the end of a 50 lap race, it told us we went about 2.5 miles. Well, in real distance, 50 laps on a 50 foot track is not even one half mile. So, I thought it might have been scale... but then it should have said 16 (or so) miles.
This lead me to wonder if the distance is being calculated by meters and then converted to miles, and so RCS64 thinks my track is 50 meters long. But, that doesn't match up. The only thing that matches up is if it's showing me kilometers, based on the track length in meters... ignoring the fact that I chose "miles" on the main page. 50 laps of a 50 meter track is 2500 meters, or 2.5km, which is what the race result screen showed under distance traveled... though without the "km" indicator.
So, I guess maybe it's a bug? RCS64 isn't converting to feet and miles when the Miles option is chosen.
