Temperature Compensation Algorithm?

Now that my Pool Pilot Nano is installed and running, and I am noticing that the displayed percentage is changing day to day. I assumed that the temperature compensation algorithm would run in the background, unseen by me, but I guess I was wrong.

Is the change in percentage that I am seeing actually the temperature compensation algorithm in action?

If so, it is working opposite of what I expected. When the water temp goes up the SWCG percentage goes up, and vice versa. This implies that it is harder to generate chlorine at higher temperature, and easier at lower temperatures. Is this correct?

Or, the algorithm is predicting correctly that there will be a higher FC demand as the temperature rises, so it compensates?

The percentage setting is proportional to how much chlorine it is generating. Higher temperatures require more chlorine, so it turns up the percentage.
