Jeffs cold water method is good. Gives you ripe honey or unripe. I use it when I first start jarring up the buckets. It is quick and easy. Later I do the refactometer readings
I guess I just to have the quantitative figures comparing one year to the next and being a spreadsheet man I had to have a refactrometer to measure exactly the water content to enter in the spreadsheet.
I grew wine grapes in an another life and a refactometer was a must to show when the sugar content was up high enough to pick the grapes. Much different scale though.
