While I fully agree with the recommendations on crush, etc., one area you might want to look at is how you calculate your expected OG. For example, I use BeerSmith 2, and experience tells me that my "Total Efficiency" should be set to around 70% or so, for the 1.050 - 1.070 beers that I brew most often. That number matches my current process well - I used to be down around 62 - 65 % when I first started doing all grain, but improved as I fine-tuned. If I would set my efficiency to 80-85% or so, I would easily read an "expected OG" around 10 points higher than I'm really likely to get.
