I just brewed up my Christmas Ale yesterday and wanted to try adding the 1# of honey that I usually use in the process after primary fermentation. I have researched this and some say it may impart a little more honey flavor instead of fermenting out.

The question is what can I expect it to do to the OG? It measured at 1.064 yesterday when put into fermentor and normally I like it to be about 1.070/72 so that it finishes about 7.5% ABV. Again more research here says that 1# should add 7 gravity points divided by how many gallons I have in the fermentor. I have 4.5 gallons so assuming that I am doing it right with the numbers and calcs I get 1.071? Am I on target? Am I doing it the correct way?
