Having a documented standard would make both AC and instrument modeling easier. Either approach could work and I could live with either. With the "jumper" approach, we should also have a fraction required such as 0.8 or 0.5 used in the power test as you suggested. In the pa24, with out the engine running and current being drawn, the battery actually discharges and w/o such a fraction required, the instrument would immediately fail with just the battery power which would be very unrealistic.
