I thought that Fred had done some voltage measurements a while ago with a
voltmeter on the pinouts and got values that suggested the scaling factor
was correct and that the voltages measured matched up with the voltages
displayed in debug menu? I suppose the values don't really matter that
much, so long as they are consistent, and range from 0% to 100%, but it
would be good if the actual voltages were displayed!
