Since posting this message, I made contact with Canon support again and this time I actually received some logical answers. The shutter count sub- menu within the battery info menu measures battery condition by counting how many shutter actuation's you have taken per battery. Every time you recharge a battery, the count goes to 0. Over the life of a battery this number will drop. To measure the actual shutter actuation's , I had good results with EOSCount.com. Its cheap and accurate. : )
