Timing I would recommend is bulk for 4-5 hours, absorption stage for 6-8 hours, and then float settings. I would suggest engaging the bulk situation after a 40% DOD."

Right-oh; that sounds like a reasonable charge regime (although it's
missing the temperature-dependent changes; presumably, it's at the usual
60-whatever-degree reference temp.)
Thanks to the pointers from everyone here, and my own research with that
info as a starting point, I'm starting to feel like I'm getting a pretty
good picture of the region that AGMs operate in - i.e., I'm starting to
feel comfortable in having a "second sense" about whether something is
right or wrong in this regard. Thanks very much to everyone who
contributed to this thread - that's what I was looking for!
