Sorry, I have no idea - but regarding bar pressure, I have always wondered why so many ask about that for hydrofoiling ?
As even the "heavy dogs" with loads of bar pressure when riding a TT or Waveboard, are featherlight (compared) when used for hydrofoiling (at least like I ride), as the kites are often two sizes smaller here, in the same wind, or said differently, a kite size is used in maybe only half the wind when foiling, as when TT jumping.
Meaning, if I use an 8 m2 on a TT it might be over 22 knots, but with a hydrofoil the 8 is used from 12 knots, so no bar pressure in this low wind, compared - and sometimes it could be good with MORE pressure hydrofoiling, so you have a better feedback and feel
You probably ride much more powered than I do, and then I understand your problem with too much bar pressure, on some kites
