Contrary - due to lack of control, the fuel timing was set non-optimal from the beginning, so that at it's normal operating speed, it was being injected at TDC or as close to it as possible, to prevent this very occurrence.

That's part of the reason I keep saying that power wasn't the main point of the experiment, and was only measured as a metric of efficiency per air temp/fuel consumption.
