Winter Sextant Sight Accuracy?

How tight a fix are other folks getting with a sextant in winter conditions? I ask because even on a fixed beach, I notice it is harder for me to get a good position in the winter. The low altitude sun sight makes atmospheric effects (eye height, temperature, barometer all affecting refraction) way more significant and I'm wondering how much this affects everyone /vs/ just how good or bad I'm doing. My last cluster of sights were within 1 mile (+-.5m) of each other, but still off by nearly two miles in absolute position. On the brighter side the bearing was within one degree of the same on all of them. I think I found some of my errors but was wondering how much better anyone else is doing?
