 This is only limiting the speed, the speed you will actually reach depends on:
 * The [battery](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Battery) you are using, higher voltage will result in higher speed
-* [Control type/Control mode](https://github.com/EFeru/hoverboard-firmware-hack-FOC#foc-firmware), Sinusoidal Control Type is faster
+* [Control type/Control mode](https://github.com/EFeru/hoverboard-firmware-hack-FOC#foc-firmware), FOC is slower than Sinusoidal Control Type as it limits PWM duty cycle to ~90% for current measurement, but it's more efficient and makes freewheeling possible
 * [Phase advance/Field weakening](https://github.com/EFeru/hoverboard-firmware-hack-FOC#field-weakening--phase-advance) can help operate the motor at higher than rated speed
 * Type of [wheel/wiring](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Hoverboard-Wheels) and wiring, Delta wiring will result in higher speed
 * The [input calibration](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Input-Calibration), proper calibration will make sure you use the full input range
