Good post, and I think there is a lot of truth to it and that its not just CICO that matters. Carbs are probably more efficiently absorbed and stored as fat when in excess. There is also probably an optimal macronutrient ratio that allows for maximum gain and retention of muscle mass when gaining or losing weight.

Then I added white rice back into the equation and cut the fat, to a 2600-3000 calorie, 30/30/40ish diet. I gained ten pounds more or less immediately with no other changes

I trust your tracking, but are you sure that some of this wasnt water weight? And/Or that you didnt gain muscle? Did your waist circumference go up? Adding back carbs will almost certainly spike water weight if youve been keto for a while.
Either way, its important to look at changes in body composition as a whole (%body fat, waist circumference) as opposed to just weight alone, which is something that most dont realize when they are trying to lose weight.

Best to settle of a set of macros, wait three weeks to see changes and make minor adjustments in three week increments. "Minimum Effective Dose" When your macro changes case to drive results, make minor changes again.

Trying to measure absorption is impossible to do accurately can change regularly due to things like body temperature, inflammation etc.
