Is the brix side correct?
That doesn't make sense to me either. I do not have the dual reading refractometer, just the Brix side. And my simple math conversion is Brix x 4.4 gives me a decent estimation of the SG. Based on his two photos the Brix reading and the hydrometer are basically the same at 1039.6/1040. However his SG reading on the refractometer is way off.

I'm open to interpretations.
This is my understanding of the problem.

Gravity to Brix Accuracy Typical dual scale refractometers use a linear 4 x gravity to Brix conversion. That’s fine and dandy up until around 1.049. At that point this linear scale starts to become inaccurate. Brix 11 does equal 1.044, but Brix 12 does not equal 1.048. It is 1.049. It’s only 1 point off here, but up at Brix 24, it’s up to 5 points off. Brix 24 equals 1.101 not 1.096.
This is my understanding of the problem.
