What is misleading in the comparison of the speed at various RPM's of the three props is that the loop prop is faster than the others at all RPM's, but that could be because it has a higher pitch or because of its design, the water slippage is less.
But what is the WOT of each of the props? Maybe the non loop props can achieve a much higher RPM and go faster than the loop prop which may be at WOT at 5,800 RPM. Maybe the prop pitch chosen for the non loop props is too low and a pitch higher would result in better results. I would rather trust the prop testing in the hands of independent testers, not the manufacturer, as they can manipulate the results in their favor by selecting less than the best prop for the others.
What market are they going after? Racing, high performance, utility, tec.
After they are in production, it would be interesting to read the results of a head to head comparison by independent testers of one of the loop props against the best stainless steel props produced by Honda, Yamaha, Evinrude, Mercury on the same boat, where each prop manufacturer is free to select their best prop for the real life water test.
Presently, the Raker 22" pitch and SRX 23" pitch are the fastest for my Glastron/Carlson CVX-16. Should I expect a loop prop to go faster? I have my doubts.
