Summary
Using 14 Lbs of Grains 11 Maris and the rest specialty malts mashing for 60 Minutes and fly sparging(7.5 Gallons) for 40 minutes in a 10 gallon cylindrical cooler with a false bottom I get a gravity reading after a 90 minute boil with 5.5 Gallons remaining of 1.055. Promash says that I'm 58% Efficient. I took a gravity reading of the wort coming out of the cooler after I had sparged off 7.5 gallons and at 70 deg's it had a gravity of 1.026
Grains
--------
Grains were crushed well by the brew shop, and they have validated that the crush produces efficient mashes.
Water
--------
I have pretty much prefect water, similar to the profile of czech pilsen region, so I add 5.2 to my mash.
PH: I did not test the ph so I don't know.
Mash Process
--------
Strike water temp was 161 ish and my mash temp hit about 152 ish. I stirred at about 30 minutes in and sparged with 180 - 200 deg water. I know 200 is to hot(husk tannins) but I wanted to try and give the sugars the best possible rinse. The interesting thing is my mash temp never seemed to get about 150 during the sparge process.
Boiling, my boil is a slow simmer, I could increase and boil off more wort allowing me to sparge more wort in the first place getting a better effiency?
Gravity of the wort still coming out of the mash after pulling off 7.5 gallons was 1.026, this makes me think that I have good conversion, and the sugar is there, but It's not getting rinsed. Also If I had channeling, then those sugars would still be on the grains, and I wouldn't get such a high gravity reading of the wort at the end of the sparge.
Am I boiling to lightly and I just need to pull off more wort?
Getting frustrated because I don't want to base all my recipes for 55% eff and buy a bunch more grains.

OG in the fermenter was 1.055
So I didn't take a gravity reading before I boiled, just when complete. I boiled for 90 minutes
