Yes Joshua, I do but need to know a bit more about it first. I'm stuck
in Melbourne at present, but will be back in the bush next week. I have
a couple of particular tracks I often walk the dog along, will log then
repeatedly and get a range of HDOP numbers and see just what sort of
difference it makes. I am trying to decide on the best strategy, if
average HDOP is above a certain number, advise to reject the whole track
might make sense but sometimes I am seeing tracks that are pretty usable
if you just cull out the bad ones (as the script does now). 

I am a bit surprised OSM does not talk about it a bit more. Will get
back to you but not immediately.
