the segments will come apart or start chipping off of the comm and it can ruin the end bell and also lock the motor up. let alone cause you a big head ache especially during a race

in engineering terms a micrometer would be best and you should check the dia. at the top middle and bottom and record the difference.
if u had a dyno as well u can check how its effected performance.
