Are you doing anything to your water? This could be adding to your problem. Poland Spring, as indicated in your recipe, has very little minerals in it. What's you mash ph? When I moved 3 years ago I had to start playing around with my water as I have well water that is no good for brewing.
I moved to distilled with salt additions and once I started monitoring and measuring my ph, and adjusting as needed with either 5.2 buffer or acids I got a 10% increase in my mash efficiency.
I now build my water and add about 1/2 the recommended 5.2 buffer and consistently hit 80% when I batch sparge and 70% for no-sparge.
to be completely honest I have not taken a mash ph OR the ph of my Poland Spring water so it seems to me that this is where I want to start and see if I find anything off here. do you all agree?
my stupidity for not checking the spring water it just tastes so good I figured why bother
EDIT: I think I will also incorporate the batch process tri9er mentioned as well
