I've been using brewtoad for my last 3-4 all grain recipes. Each time, the site gives me a really high estimate for the OG. Example: when making a rye porter today, Brewtoad gave me an estimate of a 1.075 OG. I tested my pre-boil gravity and it was 1.040, which I estimated would end up around 1.050-ish post boil. Added a half pound LME late in the boil and ended up with 1.057. Previously, I thought that it was too course a mill, but I've been milling it finer and have even switched to getting premilled base grain from morebeer.
I have my efficiency set at 65%. In order to get closer to what I'm actually getting, I'd have to scale it to 10-20% on Brewtoad. Am I missing something? Anyone else had problems like this from the site or am I just getting bad efficiency?
Here is the grain bill for the recipe (note, this is for a 4 gallon batch):
2 Row malt-5.5 lb
Rye malt-2 lb
Munich malt -1.5 lb
British crystal 70/80 - 0.5 lb
Flaked barley- 0.5 lb
Black pattent-=0.4 lb
