then i run it in like usual and take note of the amperage. then i run it on the track... if it feels good on the track then that is my baseline for gauging my motor. as long as it breaks-in around the same amperage as that baseline and feels about the same on the track, then i know its still good... if it pulls a lot more or less amperage on break-in, then i know that i need to check to make sure nothing is hung-up, or worn out... sometimes its just the natural change of the motor as the comm wears...
i guess in short as long as it feels right on the track, dont worry about the numbers on the bench...
