I'm not surprised at the MCT's not showing much with the background of a more ketogenic diet. I thought that might be the case earlier, but I didn't say anything earlier. Maybe you'll accept a retroactive prediction?

Probably not enough days of data here--but more level ketones suggests to me that the fluctuation over the course of the day with the "normal" low carb diet is likely due to the fluctuations in gluconeogenesis/liver glycogen caused by meals.
