At 8 minutes Gunnar says what it is like at over 25 knots strapless.
It may be that because the wings have to work together in a particular way to provide pitch stability, there is a range of speed where the pitch is stable, and beyond that range the behaviour is different to what happens with a traditional foil at top speed.
A mention of someone trying the Zeeko Spitfire XLW in waves while on holiday in Fuerteventura.

With Philippe, we return from two weeks to Fuerteventura, where we made foil in the waves, and we fed ourselves well!
There were two muscular sessions in Cotillo, with 25/30 knots and 3 meters of waves, and there is no photo, we used a surfkite.
By cons most of the time there were 10/15 knots and 1 to 2m of waves, and it was magical wavefoil, often almost alone.
About ten years ago, I said: When conditions are good I do the board, and the rest of the time, kite. Today is: surfkite when it's good, wavefoil the rest of the time. The difference is that instead of starting to sail at 15 knots, now it's 8 knots, and that multiplies the number of sessions by 2 or 3. (racefoil ride when it's flat, but is rare in Crozon).
Philippe had a Zeeko spitfire XLW (matt cut to 80cm) and me a Frankyfoil (wing 800, short fuselage, micro flat stab, mat 80, 2.2 kg). We could exchange and compare. I found the Zeeko stable, easy, handy, with the enormous quality of not wanting to get out of the water down the wave. Similar lift and radius of curvature. On the other hand mine is much more nervous, the glide is much better, and the speed of rotation much faster, the impression of lightness is incomparable. The Zeeko is perfect to start the wavefoil, then there is more fun, but more technical.
