That calculator appears to use a sugar potential of 46.0 pts/lb rather than the more precise 46.2 pts/lb. Errors are small, but definitely better than not compensating for the sugar volume.

Ah, of course, I should have considered from the very onset that 1 lb. of sugar added to 1 Gal. of water would not yield 1 Gal. of sugar water.
