I also think it unwise to make blanket statements regarding AGM charging. My AGM batteries require 14.7 V (77 degrees F) for bulk charging, suggesting the manufacturers specifications should be followed and AGM batteries can differ by manufacturer.
You're confusing bulk with absorption. Bulk is a fake stage where your charger is too weak to raise battery Volts to your 14.7V charging spec. That is when absorption begins. Fewer charger Amps result in longer bulk times.
Using temp comp charging, you could hook your battery to Hoover Dam's current so long as you maintain 14.7V. Bulk might take a nanosecond, after which 99% of the charging would be done during absorption.
IMHO and YMMV. :)
