Flipsky and Trampa getting two very different detected resistances on same motor!

I have a two identical Flipsky BLDC motors: sensorless 85165 inrunner 200KV. They are rated 19kw max, 8500w continuous. I'm running 52v and 300A max.

I have two Flipsky 75350 FSESC's which each detect the motors each right around 7 mOhm and detected Inductance is 7.6.
I also have two Trampa 75300 MKIV VESC which each detect the motors each right around 4.8 mOhm and the detected Inductance is 8.6.

Which values should I trust? They all seem to run ok so far, with the Flipsky being the smoothest starting from zero, but current faults when pushed beyond 80% duty cycle under load.
I have read that the resistance value should be within 5% accurate to work well. These values are ranging slightly more than that! lol

Any ideas? Anyone have experience with these motors can say what they should be? (Flipsky support is not very technical).

Thank you!
