does this calculate speed?
Makes me feel tired to watch that stick figure guy pumping for so long!
How should a rider use/benefit from this? (Not being critical, just curious how I should use it, e.g. Can this tell me if I have the wrong dock start foil? Choose a dw foil size?)
If Iām correct, you could type in your set up with weight etc and it tells you the most efficient way to ride it. For example which ampliute at which speed. Or you could change the parameter to a smaller stab / smaller front wing or a different angle of attack and see how that would play out. Or losing bodyweight vs gear weight 
.
I was listening to the podcast here and really enjoyed it! It also made me understand better the benefits of this simulator.
The difference the body weight makes is amazing! 70kg - 220 watt vs 100kg 380watt pumping a 1300sqm front wing
