I can only surmise you're not comprehending what's taking place. The factory voltage setting is 14.1V. MrWiz cranked this setpoint voltage up to 14.7V. Gassing begins above 13.9V. It's important to note, gassing is a function of battery voltage, not current. If the battery voltage rises to 14.6V, then there's enough current to make it happen.
As a homework assignment, do your own research & analysis to the rest of your questions.

How can the controller crank out so much more than the battery will accept and create this gassing problem when it is designed to not do that?
