Oke I test again now only he just had his raw food....Try stalling twenty minutes and retest - no food. If he is sure rising, not falling, you might try a reduced dose. I'll watch to see what you get.
Hmmm. I am cautious about giving a normal dose on that normal number because of the food given and the fact that the numbers are gradually lowering. I can't remember - are you going into night or day? Can you monitor at +2 and +6? If so, maybe 2.5 If not, 2.25 My theory is that it is better to undershoot a little than overshoot.
Then, unless you want to stay up and monitor, I'd go with the lower dose.
