If you want to increase the sample rate, you would need 6 separate lasers flashing once every 0.03 seconds; not a single laser flashing 6x per revolution.

Take a video camera and record one reference spot on the wall. When playing back the footage, increase the playback speed and you should see how much the speed varies. The biggest argument against using the timeline is that only measures average speed per revolution. The trick is to increase the sample rate to more than once per revolution.
