I assume that FOC is a more efficient way to drive a motor. If not then what's the point? Why not just use a cheap trapezoidal ESC? Can anyone give any anecdotal evidence that this is the case?

I was wondering the losses in the Vesc compared to the motor or now that it's brought up how about also compared to hobby part esc? What would be the losses at half duty cycle vs full for both the vesc and motor, generally?

Seems a typical bldc motor will have some semblance of trap and sine and it's complicated
