could do some uploading (bulk) have six months of track-logs but 90% on side-walks, does this make a difference?

Please don't drive a bike or trike on the sidewalk, you make yourself invisible to motorists turning at intersections and entering or leaving driveways, not to mention you put yourself at conflict with pedestrian traffic: The overwhelming majority of all bicycle wrecks could be prevented by not driving on the sidewalk.
All states consider bicycles as slow moving vehicles and provides legal provisions for safe operation on roads open to cyclists, rendering the practice of driving a bicycle on the sidewalk unnecessary, and many cities prohibit driving a bicycle on the sidewalk entirely (if not city-wide, within the downtown core).
Much safer methods for mapping routes that are relatively difficult or dangerous by bicycle, but do have sidewalks are better mapped by foot or car and should probably be tagged bicycle=destination to prevent routing algorithms from considering the way as anything more than a way of last resort for cyclists.

The accuracy of GPS means that tracing a road from the side-walk is usually pretty good and certainly much better than nothing. If I drive or cycle down a road I'm still not on the centre line.

If your GPS gives you good data (repetitive walk will get you good data too), then you will get two different track lines even when driving in both directions. So, yes, it makes difference. But the difference is small. Uneditable by Merkaartor as of yet, as it is not possible to zoom enough to make so small corrections. Website editor can zoom so much in.
