AGM Adventures- Update
Updated 31 Jan 17 Initial results. I will re-test the AGM after it does one deep cycle to confirm these results. EDIT completed 6 Oct Test was to put the test battery as the only battery run...

Well, ideal absorption voltage is temperature related.
If this battery heats a lot during charging, normal ambient temperature absorption voltages could pop those "27 amp" vents.
In your intended ultimate location in the TC, will the battery get any ventilation?
My group27 battery is rated at 2.8 m ohms resistance, yours is 4 pounds lighter and 5 m ohms resistance.
Me does thinks your battery done get mo hotter than mine would at same charging amps.
Mine got hotter than I expected when i put a temp sensor on it.
Just make another column on your chart :)
After I saw temp rise I thought temperature rise/retention after a high amp recharge was responsible for apparent faster engine cranking and higher voltages held during subsequent recharges.
The battery temp sensor allowed me to rule that out when that variable was removed.( battery allowed to cool before engine cranking or overnight discharge)
