Hi @rschmehl , do you think if PhD project could provide an answer to my question on

Does a soft crosswind kite really maintain its efficiency as the wind speed increases?

Today I tested my Peter Lynn Vibe of 0.6 m² at 8 m/s wind speed instead of 4 m/s wind speed, with large crosswind figures or tight loops, obtaining about 9 kg traction (instead of 3-5 kg with 4 m/s wind speed according to several measures) which was measured with a steelyard at each handle. But the pull should have been more, about 12-20 kg, knowing also that 12 kg value compared to 9 kg falls within the margin of error. If we analyse the data on the table 8 page 44 of https://repository.tudel…
