What I'm thinking is that this would be the same as a float charge. Battery tender has some charts putting float charge at 50-100mA

Agreed. Charging and discharging efficiency is a miniscule drop in the overall efficiency of petrol vehicles. Charge efficiency only needs to be considered in systems where they are heavily used, such as EVs, alternator deletes, and hybrid traction batteries.
Regardless, I'm curious, and I don't see much information available from internet searches. My ultimate goal is to do an alternator delete while preserving as much convenience and longevity of the battery as possible.
