MPPT60 Morningstar Setpoints

I’m seeking help and understanding on setting the Custom Setpoints for my Morningstar MPPT60 controller. The solar setup is 3x250W Cynergy series panels for Vmp =91.7 and Imp = 8.2. The batteries are 4x Lifeline AGM GPL-4CT 6V configured for 12V 440AH. I have the battery voltage set to 14.3V for absorb (spec 14.2-14.4) and 13.3V for float (spec 13.2-13.4). All of the remaining settings are the default settings.
What are the considerations and how can I determine the remaining settings? In particular the settings with their current values for Absorption Time (2:30:00), Absorption Ext Voltage (12.50), Absorption Ext Time (3:30:00), Float Timeout (1:00:00), Float Cancel Voltage (12.30), HVD (14.50) and HVDR (13.80).
It seems likely that the setting will be dependent upon usage but I want to understand what to consider so that I can make reasonable settings for the controller.

The manual barely covers this, I'll try.
Do you have dip switch settings for AGM/sealed batteries and to disable EQ ??
Absorption Time (2:30:00) How long the batteries dwell at Abs voltage to complete their charge. Can be deadly to AGM, if they are near full. I would for sure lower this, does your battery mfg give any guidance ?
Absorption Ext Voltage (12.50), If some night, the batteries are really drained low, below this voltage, the next charge cycle will have a longer (Extended) time
Absorption Ext Time (3:30:00), How long for the special extended time.
Float Timeout (1:00:00), I think it's the time required below the Float Cancel Voltage, to restart a charge cycle (Bulk, Absorb)
Float Cancel Voltage (12.30) voltage to restart charge cycle

Ask Life Line for their opinion if you want your eye's opened. They have changed their recommendations and are even recommending light equalization due to all of the problems with the average user undercharging. If you charge all the way up, you don't need to equalize AGM's, but undercharging them leads to death.
