I, like many who use JOSM, do the same, ie we load our raw gpx files from
our fresh mapping trip into JOSM in order to edit. In some case I may turn
on the draw lines between points but generally I do not need it with a 1 sec
point drop. Then I colour these gpx points so they stand out before doing a
map data and gpx download from the OSM API, I can then see existing gps
points in one colour and my new gps data in another colour. Finally when I
am done editing I upload the new gpx files to OSM so everyone can use them.
