Accurate repeated waypoint routes

[Myersfilm]

I have been capturing the process of construction sites and have had trouble with the waypoint paths staying true. My Mavic 3 pro will drift from the original routes logged making it hard to align in post editing.
Any suggestions to creating a accurate repeatable waypoint routes with minimal inconsistencies?
The advice that I have gotten is to create many waypoints within the route, or to set the mph low, or to calibrate the compass and update the home point in the same place every flight.
I appreciate any input.

Hello from the Crossroads of America Myersfilm.

Nice to meet you.

You might try the sites search engine (Magnifying Glass, top / right of browser).

Others will be along and may have better advice than me.

The compass has nothing to do with gps positioning so I wouldn’t bother calibrating it before each flight unless the app requires it and even then I’d shut the drone down and move it and check again before calibrating. The accuracy of gps positioning and therefore waypoint positioning has more to do with the number and spread of gps satellites. Civilian GPS can be as accurate as 0.5m but can easily be 3 or 4m out.
