Take a look at the videos

on the qajaqusa site and see what you think is their stroke rate.
I did some estimates of Doug van Doren in his greenland kayaking video and I kept getting 90-110 strokes/minute. I could never get close to that. When I got to paddle with him in person I was just amazed at how relaxed he looked, but how fast he could turn that paddle over. I would be paddling along barely keeping up with him and then he would decide to jump ahead to another student up ahead. No particular sign of extra effort but the stroke rate would look like he almost doubled it and off he would go leaving me behind.
Good luck in your experimentation.
