As a rule of thumb, one gets an improvement of ~one order of magnitude with augmentation. Not quite so good with WAAS as with truly local DGPS, and nowhere nearly as good as RTK. We were able to get, in the old days, with SA on, <10m accuracy with DGPS, and 15cm accuracies with RTK, assuming a good correlator and stable oscillators. This was when we could document >90m induced error with SA.
