OK, I'm an idiot, don't "PowerFLARM units also include an IGC approved GPS flight recorder?"

Good question! Yes, it certainly does.

"This option will enable you to prove records up to and including diamond badges in accordance with FAI Sporting Code. The option adds a strong cryptographic signature to IGC files as well as enables task declarations. The pressure sensor is uncalibrated, since calibration isn’t necessary for most flights."

The IGC file format does allow for airspeed info, of course, but PowerFLARM does not record Airspeed records in its IGC files, which are limited up to the three diamond badges.
