I think its actually just from the fact that the powertap stops my garmin later than the quarq. As soon as you come to a stop on a Quarq its auto pause. With the powertap, it takes a few more seconds as its still reading some speed. It's hard to explain but thats why the powertap has an extra 40 seconds of moving time than the Quarq.
