A low EPE means that the GPS thinks everything is fine even though those estimates are less than what is possible with the technology. It isn't the errors that I ignore, it's the EPE. Higher EPE means that there are real errors creeping into the position readings and I make sure that I consider that when looking at the reported position. Even at SA levels of error (<100m, 95% of the time), that's still a lot better than what you can do with a sextant, so error interpretation is relative.
