Shore Power and Batteries

In an insomnia moment last night, I got thinking (scares me too ). If one were to believe Nigel Calder you get maximum use from batteries if they are allowed to discharge to near 50% before recharging. Am I prematurely killing my batteries through my habit of plugging my boat into shorepower and therefore the battery charger whenever she is in her slip? I tend to use my boat close to every weekend for daysails, so in reality she is on shorepower about 90-95% of the available hours each week, I would estimate that I am only discharging my batteries by 5% or so when she is out of the slip.
