It happen that all wpts are like this.
Not a big issue for me.
I just want to be sure that something is not bad tuned
This is a large route. About 1 km between wpts

Check out the NavL1 tuning.

The wiki says that the NAVL1_PERIOD default is 20, but some time ago it went down to 17.
Lowered to 15.
Yes, it was 17 as default.
I will update next flight!
