What I do is: 
 - Take my gpx-,mps-,...-tracks
 - convert and filter them with something like
     osm-filter.pl --out-osm --use_reduce_filter gpx-*.gpx 
 - load the resulting osm File into josm
 - in josm edit it as of deleting duplicates, glitches, ... 
 - then tell josm to upload that to the Server.
