I'm a bit loathe to even try guessing.

They seem to have been very careful in what they have actually said, like "within 10% of modelled results", but they have not aligned those modelled results in any way with the stated output of 240kW.

Maybe 240kW is the maximum a single buoy can generate, if you attached it to a godzilla-powered, buoy-pumping-up-and-down machine, but what were their modelled/predicted results for actual in-ocean performance? All we have seen for sure is a 20 minute period of measured results of one buoy running at 17% of that 240kW. God help us if that was what they modelled.

Take a solar system, like the two I have. An individual solar panel might be "190W" or "250W", but for them to produce that amount of juice conditions need to be perfect. Perfect sunlight, perfect angle, perfect temperature (not too hot), etc. In actuality on any given day hitting 90% of that rated wattage is good, and output from sunrise to sundown is a bell curve, so you get that 90% for maybe 2-3 hours on a good day and less for the rest.

If CWE had data showing that in the wild CETO 5 ran at an average of even 50% efficiency over time it would be incredible, incredible news. And then you ask youself "why wouldn't they announce such a thing if it were so?", and you* go pour a scotch.
