LCR meter help

What would be a range for in milli-Ohms for motors? Like 17.5 - 21.5T specifically. I'm guessing as long as the meter will read from 0-100 milli-Ohms with good accuracy, then it would work well.

ROAR currently specifies resistance only for 25.5 motors (101 milliohms at 25C). Reasonable minimum resistances for the other motors would be:
10.5T: 15.5 milliohms at 25C
13.5T: 25.0 milliohms at 25C
17.5T: 42 milliohms at 25C
21.5T: 64.9 milliohms at 25C
10.5T: 15.5 milliohms at 25C
13.5T: 25.0 milliohms at 25C
17.5T: 42 milliohms at 25C
21.5T: 64.9 milliohms at 25C

Is that a single pole (A) or two poles (A+B)?

My apologies, I should have stated the conditions. This is the resistance measured between any two stator terminals-- A to B, A to C, or B to C. No motor disassembly is required, and in most cases one does not even need to disconnect the motor from the ESC (but the ESC must be disconnected from the battery).
