Just took a sample of a fully fermented beer. Hydrometer: 1.012. Terill: 1.010. Novotný: 1.008. Maybe I'll use refractometer on brew day, but maybe neither correction is really accurate on fermenting/fermented beer. Look forward to more data.
Are you very confident in your correction factor? Did you check calibration of both the hydro and refract in plain cool water before measuring?

Terrill New Cubic or New Linear? New cubic tracks a bit higher than New Linear.
What was the O.G.?
OG 12.7°P, whatever Terill is in th OP's calculator, yes, yes, and yes to Dave's questions. I've had one other sample (fully fermented, different batch of same beer) give identical results.
At this point I have no problem with using a hydrometer at racking if I want a good FG. I see no inaccuracy on wort, so the refractometer I will use to simplify brew day. And I'll only have one reading, FG, to convert to (my preferred) Plato.
