Or is the difference not significant enough to be a factor?
The higher BB on a track frame is to prevent pedal/ground contact on the outside pedal when going around a steeply banked track, which ironically, allows you to pedal around the track more slowly. Running longer crank arms on a FG is a bad idea, even with a higher BB. With one gear an no ability to coast shorter cranks allow you to spin faster more comfortably.
