BB says to wait 20 minutes per battery to be sure the battery is balanced, and Trojan says 10 minutes (for one battery?), but whatever---it takes time to get that done, so how can it be a good idea to stop the charge as soon as you get to Vabs (which needs to be over 14v--ISTR BB saying it needs to be 14.2v but they also say over 14, so whatever)
2.For your Bulk/Absorption stage, the ideal voltage is between 14.2v-14.6v. For full charge and BALANCE, the absorption mode should be set to last for at least 20 minutes per battery (for multiple batteries in parallel).
I don't think a "good old boy" approach (if all else fails, read the instructions) to LFP charging is appropriate considering what LFPs cost, but YMMV.
Though I found this of no relevance, maybe you can find the answer to your question in what you’ve previously offered :
