Mmmm, not exactly. ZZ.com has it as...
Feet Per Minute * 60 = Feet Per Hour
Feet Per Hour / 5,280 = Miles Per Hour
Miles Per Hour * 64 = Scale MPH
Not to mention their method doesn't take into account any kind of real world conditions or load.
My way is SIMPLE...Just divide 900 by the time (in seconds) when running on a 20'7" stretch. That's it, that's your MPH (to scale). My way calculates from ACTUAL distance traveled at a certain time (so this is actual scale MPH)
While 10' is probably more convenient to folks, it's NOT a good indicator of actual TOP SPEED...10' just isn't enough for these little demons to get to their top end.
If anyone is interested, I can create an Excel spreadsheet and you can plug in WHATEVER distance you decide to use (10ft, 20.625ft, or whatever) and it'll automatically churn out the scale mph, based on runtimes.
