You have to satisfy the chemical demands of your battery, not a calculator. This is where E=MC2 meets reality. Unless you put Velcro tabs and wing nuts on your battery hold down.
When a charging protocol just meets the sanctification of battery chemistry is the real world goal. And only a hydrometer can determine this with a flooded battery after a month or six weeks of service. AGM capacity tests or the half-percent rule has to be met.
The above rules for extended boondocking. The 3 days to a week usage then suckle at a power post can get away with murdering the extended boondocking/E=MC2 reality.
