Did you notice that, before GO4 app existed, some previous version had slower RTH descend rate? I think since some 3.xx version or P4 firmware they increased RTH descend rate. I remember very well I did some RTH demo and was shocked seeing the craft having higher vertical speed descend - I add throttle and finally cxl RTH as safety. Imagine if it was auto RTH following RC disconnect: possible hard landing or worse..
I think at some point DJI must have increased RTH descend speed for wathever reason, but I have not seen any information about this. Just my experience. As per result, the craft might apply agressive breaking when VPS takes authority as seeing (if he can) the ground within last 10 meters or so.
I understand craft is only able to have linear vertical descend speed, until close to the ground were he realize it's time to apply breakes. Because he doesn't know exact altitute as already discussed in this forum (barometer).
Increasing RTH descend rate looks on my opinion more risky as possible hard landing or crash if VPS confused: less buffer when reaching the ground. So reducing speed for the last 20 meters instead 10 would be smooth but I doubt it's possible with current design.
Any though welcome.
