Hello Juaki
Sorry for the late response – for some reason I did not receive any notification for this.
At any rate, yes, FTV works with GAP2021, and has been used like this in numerous paragliding competitions world-wide.
Just be prepared to answer a lot of questions from pilots when they see the results. Depending on your timing, I may be able to give a short intro to FTV over Zoom. The best way to reach me directly is joerg.ewald@volirium.com.
Happy Flying, and good luck with your competition!
Joerg
