Assuming no lies, you'd really want to see a chart+table of voltage vs time as the component is discharged through a resistor. That would unambiguously prove how much energy was stored. The table above leaves a bit of room for doubt -- just because K is 20000 at 0, 3500, and 5000 volts doesn't mean it's 20000 at all intermediate voltages.
But Burke would not have been satisfied with data, because he thinks Weir might be lying, and people who lie can just make data up. Burke would have needed a component to test himself.
