Jack, if that can be verified then the starting voltage can easily be modified with a resistor in the sense circuit. (Our guy Peter V can probably figure out the value of the resistor if we stop picking on Marathons).

The only problem then is the question about the six hour run time. It won't hurt anything except burn more fuel than required.
