Jones, I don't know if we have a real ratcheting effect or not. I have it running like a simple thermostat. Turns the electrolysis on at a set temp and off at a set temp. With this method, you would only see ratcheting if there was "heat after death." The other possibility to see it would be a decreasing amount of time that the electrolysis is turned on. Another possibility would be to compare to a control run.
I would need to switch over to a fixed duty cycle to demonstrate a ratcheting effect more clearly. I think another possibility to produce the effect would be to run the electrolysis continuously while pulsing a joule heater at a fixed duty cycle within the cell. This would really be closer to an electrolytic analogue of the E-cat, because of the continuous presence of hydrogen. If I'm not mistaken, P&F had some good results with pulsing a joule heater.
