Boiling shouldn't affect your mash efficiency I wouldn't think. That's when you start getting in to your brewhouse efficiency.

Ok, must be some beersmith setting where tries to auto calc the mash. My brewhouse efficiency ended up being 72%.
I think this is the first time while brewing all-grain, i've actually achieved 5 gallons of beer. Instead of 4.5 or 4.8. However, i did adjust for my loss due to boil off and trub. Before i've never done that. I think i lose like 27% due to boil off and trub, etc...

It depends on what number you are comparing it to. Typically your mash efficiency percentage in recipes is geared towards the Original Gravity, not pre-boil gravity (since there are more factors in that). Lets see if I can lay it out correctly:
Hypothetically:
10 lbs of 2 Row should give me at 75% 5 gallons of wort at 1.050. Pre-boil I should have 7 gallons at 1.030. If i take a pre-boil reading and compare it to that 75% number I am going to be closer to 65% efficiency if I am comparing it to the recipe number. But once I boil away those extra 2 gallons I should be right on point for the 75% number.
I think I just typed a bunch of stuff out that was unnecessary. I don't use beersmith so I never know exactly what my numbers are supposed to be. But I think that mash efficiency is much easier to determine with OG at 5/5.5 gallons rather than looking pre-boil gravity.
