IMHO definitely put source=survey if it is. (e.g. from a gps track) It

E.g. I can see that there is a GPS track log nearby, but did the person
use it?
This brings up a point which I'd like clarification on.
When I input data from my own GPS, I tag it as source=survey.
But what if I use the JOSM download of "Raw GPS data" to plot the way?
What should the source tag say then?
As long as there have been more than a handful of passes logged, This
seems the most accurate way by far to get the true path of a winding
road. The "false" points (when individual GPSs can't decide whether a
corner has come up, or accuracy has gone down) get nicely averaged out.
