I bet since they are intermittant and are only really just low power dc motors essentially, they would not be much of a factor unless you left them on continously for some reason. Its an estimate, I didnt test those features, the istDS doesnt even have AS to test. I doubt anything else is going to be even close to the full power flash energy consumption. jco
