Maybe the 10 second method will work too. The curve should be the same either way, but the 10 second method will get more data points.

When I did 'em,I used an low-tech cassette-recorder,yelling the velocity points as I coasted.I did all the runs,then reduced the data at home using the stopwatch there.Sure makes a windtunnel look attractive!
