Granted we only measured 6-8ma, but why start off with a partially discharged battery. With supply side connected but without the main battery the discharge rate will be much higher (assuming things like victor fans, etc. are directly connected to breakers and not via spikes).
That's why we added a diode to avoid back feeding the spikes and victors. Too bad we'll have to take it off at competetion.
