1/8 Motors Running With or Without Sensor Wire?

1/8 Motors Running With or Without Sensor Wire?
Quick question.
It's commonplace for high end 1/8 motors to have sensors, it is also common to have ESC's with timing that only works when a motor is not sensored.
I have a HW SC pro ESC and LRP Dynamic 8, it runs great with a sensor plugged in, and it also runs almost as smooth with out it, I have heard of people saying that they ignore plugging in the wire as they have seen decreased temps and more power running sensorless (this is in a race setting).
My question is what do you folks think? I know sensorless 540 cans are terrible on a track, but these bigger motors seem to work just fine sensorless.

They work better because they have more poles. The rotor makes 1/2 revolution every time the esc switches phase in a 2 pole. 4 poles make a 1/4 revolution, and 6 poles make a 1/6th. That's why they are so smooth even nonsensored. Some esc's wont run sensorless, or will stop if the sensoer wire becomes unplugged or goes bad during a race.

I was thinking that too because the wire that is not doing anything becomes sends a signal.
But if I remember, 2pole changes phase 1/3 turn 4pole 1/6 and 6pole 1/9
there is never 1pole so 2pole= 1, 4= 2 and 6= 3 then multiply by 3 of stator segments gives you number of phases.... I think, it's been a while.
