So i am using brewzor and when i add a fermentable i see a yield %. for example my yield % for 2 row is 79% on the add fermentable screen. some like bel. wheat malt is like 80's... which i know i get a 70% eff most times. now when i back out to the edit recipe screen i see i have it set there for 70%. i dont have any other software right now and am looking at buying beersmith but i was wondering if someone could help me calculate the OG with 70% eff in another program and see if it is the same.
