short answer to determine your efficiency is to divide your measured gravity "points" by the intended gravity ie
say you have a recipe that at 1.080 and you get 1.060...60/80=0.75 or 75%(your efficiency)
Thats not right is it? The reason I say that is because if I have a recipe that is at 1.080 and I hit 1.080 I dont have 100% efficiency. Each recipe should have the efficiency listed with it. If your OG is different from what the recipe says, then your efficiency is different from what the recipe says.

I speak of Extraction efficiency...not overall efficiency. I agree with ajdelange's method.Also I agree Beersmith and/or other software works easy to determine said numbers.
