more questions, Using a refractometer

I have been looking into a refractometer. I used more beers spread sheet

MoreBeer!™: Using a refractometer in brewing | MoreBeer. I used this as well

BrewCalcs: Free Homebrewing Calculations


and then did the old multiply the brix by 4. all three equaled three different readings

So what is the best way to use these.

The MoreBeer spreadsheet produces weird Brix to OG conversions in my experience, because it uses a very high wort correction factor. That is the primary difference between the various calculators - they all use different corrections to account for the non-fermentables in wort that slightly skew the refract reading.
In my limited experience, I have found that the BeerSmith software does the best job overall, since it lets you calibrate your Brix-OG conversion based on your equipment. Its post-fermentation estimates also were closer to my hydro readings than with the other calculators I tried.
