Do we know who makes the battery for the V7, and have we confirmed that it IS an AGM?
I'm under the impression that AGM batteries are a little more sturdy than traditional lead acids with regards to charge rate.
The first reference I find is in the FAQ page for Optima:

See CHARGING -
Also:
In contrast this website seems to favor the 14.4V limit for which you are aiming:

This website talks about battery charge rates, and shows rates up to 14.9 for fast charging AGMs.

Here's a question. Does the circuitry in this regulator not adjust to system load and battery charge need? I.E. if the battery is discharged it's going to regulate the charge rate on the higher side until the battery is properly charged AND/OR load drops meaning it can shunt more power to ground and lower the charge rate more toward 13 volts.
I.E. if people are starting their bikes (maybe some that haven't been ridden in weeks or longer over winter) and immediately putting a DVOM across the battery terminals SHOULDN'T they be seeing a high charge rate? Potentially up to 15 volts (not over)? If those same people went for a 30 minute ride and THEN connected the DVOM might they see something closer to 13?

Voltage measurements of the battery when the engine is running are the output of your alternator. This measurement should be about 13.3-15.0 volts, which may differ due to temperature. At average operating temperatures of 50° to 80°F, your alternator output voltage should be about 14 volts to 14.8 volts.
Also:
For regular charging we recommend a maximum of 10-amps, 13.8-15.0 volts. For float charging, we recommend 1 amp maximum, 13.2-13.8 volts.
