That's an acceptable method. I don't expect them to do square roots or logarithms with paper and pencil, so using Aerolab is fine. The main point is that if you have a way to record speed you can do coastdowns, get the data into Aerolab, and fiddle with it. Plus, if you do a coastdown you don't have to worry about the accuracy of your power meter -- you know the power was zero.
So, what's your answer?
