The robot is actually moving faster than any one wheel is spinning.
I meant that the net speed, all things considered, is potentially greater for a robot with four motors pointing in the intended direction of motion than a holonomic system, if the gearing is adjusted to compensate for motor differences.

Sorry about any confusion.
