But regardless, one of the things you can do is see how much of an rpm drop you have under certain loads. If you are looking for top speed down the straight use a lower load or higher value resistors. If you are looking for more pull out of corners use a lower value resistor for more load. Compare rpm drop from different timing settings. You can also do the same old test where you plot the rpm vs current draw for different timing and find where the current goes up with not much rpm gain. And you also have the benefit of knowing it was with a load.
