To be honest, I shouldn't get too bogged down on this bit; I generally 
download a small area to do mapping, add stuff, upload, add stuff, 
upload, close & restart. If there's a (time) gap I'll download it again.

This is because if you do tons then upload, & it fails, you have a 
problem. Downloading every few minutes will play hob with the server if 
we all do it! Downloading successive areas is messy & [used to] screw up 
josm - & if you've done an area, better to free some RAM & it all goes 
faster. Josm can be damn slow if you have a massive area loaded.

 If you know someone else is active in 'your' area at the same time, you 
may have to be pickier, but it's only a problem if someone enters data 
as 'new' in parallel with you. This can then give duplicate ways, which 
are hard to spot but look odd when rendered.
Worse is to save a file, then edit it & upload from old data. Or to save 
a file with uploads to go...


I tend to select a portion of a large GPS trace to download & work on, 
after an outing, and work along my route in bits; usually I will have 
done some already anyway, so this makes sense; a fresh area doesn't 
(obviously) need downloading, as it's blank - not many of those round here!
