5 sets of: 
10 strokes for peak watts
Rest AT LEAST 5:00 between sets

We're not looking for the highest average in those 10 strokes; we're looking for the highest single stroke in each set. I was reaching my MAX somewhere in the first 15 seconds, usually around 8-10 strokes in. Was pumped to break 500 watts (1:28.7 split)!
