My experiment wasn't very precise, so I'll defer to your numbers, and you've covered your bases by rounding to the nearest bar measure. I'm a math and sometimes physics guy, not a chemistry guy, so we're at the limit of my knowledge. It looks good to me. There's variability in the numbers anyway depending on the fineness of the sugar, and at the end of the day we're adjusting to taste. Thanks for the conversation!
