Motor Shaft Runout

I have emax mt2204 2300kv motors on my 250 racer. How much runout is normal on motors like this and how much is too much?

I'm getting .001 TIR on 3 of them and closer to .0005 on one of them.

How does this sound? Should I be concerded?

For their price that sounds pretty good.
The real test is Are they Balanced and not causing vibrations.
So mount them to a frame with an FC and spin them up and check the FC's Accelerometer graph.
