Refractometer vs. Hydrometer Video

.....I've given up on trying to use it for mid/FG because the correction spreadsheet always seems to be +/- 1.002. I guess if that's "good enough", it's still workable....

I was about to bring this up. Bobby, I think it was from one of your posts that I downloaded the B3 spreadsheet. I just noticed last Saturday that the spreadsheet and BeerSmith don't agree on OG when converting from Brix.
I will have to look again, but I recall that there were several points difference calculating the OG of unfermented wort.

I just found out today that my hydrometer is LOW by between 2 and 4 points... so I ordered an ATC refractometer. I use ProMash and it seems that the use of the refractometer for OG and FG will be pretty easy due to the fact that ProMash will do all the calculating for me as long as I tell it the OG Brix and FG BRix.

It actually converts it to Plato and SG and will compensate for the alcohol in the beer after the ferment. YAY!

For those of you using the refractometer, what correction do you use? 1.040? I hear that is typical.
