I just brewed my 3rd all grain yesterday and had quite poor efficiency.
1st brew, crush from LHBS I got 65% and and my FG was a little high, and I chalked it up to too high of a mash temp ~158F.
2nd brew, crush from Brewmasters Warehouse and I got 72.5% and my OG and FG were almost dead on.
3rd brew, crush from LHBS and I got 62%. Mash temps were steady at 151F for 75 minutes. OG was 14pts lower than expected.

The crush from Brewmasters was noticeably finer.
I did not do an iodine test (forgot).
Any thoughts?
Should I just order from Brewmasters and see if my eff is better?
Sort of frustrating after spending all that time and money.
