As a geocacher, I'm unhappily aware that different brands of GPS give
different results, with differences in the order of 10 meters for an
individual point. I suppose a track should be better, since there is an
internal consistency check, though not if the difference is due to
systemic causes. As it happens, in this case I had my own GPS trace to
work with, and it aligned reasonably well with the Bing image of the
path I was following.
One thing I'm not sure of: were my GPS traces uploaded with the edits,
or did I have to do something special to upload them?

Hi Tom:
welcome to OSM and congratulations on your first edits! Yes, it sounds
like you did the right thing. One thing to look out for: Bing images
are not always aligned 100% -- they can be offset by several meters.
Usually this is not a problem but if there are any GPS traces
available in your area you (most likely to be found along major roads)
you can use those to make sure that the imagery is not off. In JOSM
you get the GPS traces by checking the "Raw GPS data" box in the
Download window.
Happy editing,
Harald.
