@alex38 my understanding is the hardware has limited memory and it is hard to fit anything else in there. If there were meaningful improvements and it allowed better upgrades in future, I'd buy a new master module. A barefoot mode would be great (no room for it at the moment). Z box autocal would be brilliant (the accelerometer should be able to calibrate the Z box settings), auto tune of ball times, feedback about what the boat is doing (for example, PP knows what is is asking the boat to do and is measuring what it actually does, it would be great if it would tell us if the boat is not responding properly so we can see what needs fixing and why), ability to connect to a personal hot spot and send info back to PP, download updates etc.
Maybe they could offer a new improved display with it too?
Although us skiers do like to complain about prices, we are prepared to spend money on our sport and I think it would be great if we gave PP the confidence to invest more into us.
