I've seen the same kind of response, I don't mean your cop, but the fact that the higher the impedance/resistance of the load, the higher the output power, while amps don't change much. What changes is the input power.
What I would do to get the full picture of what your machine does I would do the following, although I'm sure you've done it already.
Use FWBR+big enough CAP on output. This makes out power easier to measure. The best load for this test of course would be a high power variable resistor, but different fixed resistors or lamps on a switchbox will work too.
The idea is to make a graph with the IN/OUT power curves at different load resistances along with RPMS.
OUT power curve will go from lowest (shorted coil or lowest resistance) to highest, then lower again (towards infinite resistance load)
IN power curve will go from lowest (acceleration under shorted output), up to a MAX, then down again to the point of highest or infinite resistance, basically an open coil condition.
Once the graph is made you should be able to find the point where the COP is highest by comparing IN versus OUT curve, sort of a bell curve.
Say you find that you get the highest COP when a given load resistance gives you 150 VDC on your cap. If your final desired load is a battery bank you could then put them in series to match the desired output voltage of aprox 150 V.
Or you could use a high efficiency DC-DC converter with adjustable output for a desired load, be it a battery bank or something else, and load it in order to have the input of the converter (or gen output cap) set at aprox. 150 V.
Just some ideas...
