Thinking in speed terms is the wrong approach because after your rolling it takes very little power to keep it rolling, slowing down, and changing direction is completely different and this is where rotor inertia, Mass, torque, etc come into play.
The fact you can travel at 50mtr.min might seem great until you come to stoping the bloody thing and it overshoots because the inertia of the moving mass and rotor together run out of brakes.
Likewise hitting the throttle hard is the same thing in reverse, so high rotor inertia, heavy mass requires lots of power to get things moving, after which hardly any is needed to keep it moving, then the cycle starts again to slow down/change direction.
It's these things, among others, which can make tuning the motors difficult, achieving high feeds is easy but not always a good thing.-use common sense, if you lack it, there is no software to help that.
