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...

seems I have all the more reason to be happy with my recently acquired CTEK Multi US 7002 charger
This statement reveals you absorbed only those things you wanted to hear.
Fact: Deeply cycled AGMS like the occassional higher amp recharge approaching that 30% rate. Some Like that 30% bumped to 40% and perhaps 'occasional' should be upped to 'frequent'.
Will the lack of this with your Ctek charger seriously negatively affect your proposed AGM battery life in your proposed usage?
I don't know, but My AGM show obvious obvious signs of being UNHAPPY with ONLY low and slow recharges, deep cycle after deep cycle, even if every recharges cycle get to the 98 to 100% charged range and my low and slow can reach 11 amps this time of year and 13 in summer, on 90Ah capacity.
Even with a 'smart' charger capable of higher than a 30% charge rate on a given AGM battery, will more likely regularly undercharge a deeply cycled AGM, than overcharge it or risk it venting.
Which again is not an instant death knell of the battery.
If your Ctek's 8 stages of battery charger marketing, and 7 amps maximum of charge current give you the confident and self assured warm and fuzzies.....
Well.....,
Congratulations!
I need at least 25 amps before warm and fuzzies can begin to set in
