waypoint stopping

[daps20]

Hello, I have an h850 I'm doing mission for mapping but drone always stops at each waypoint not just the corner ones but also the intermediate ones this is not good because average speed is lower and you can do smaller missions. I saw that by changing parameter nav_acc_rad to 5 drone will fly smoothly but by default it comes with 1 written, and if you change it to 5 it always goes back to 1. anyone has solved this issue about stopping?

thanks
