Wow, Junior really moves around, first time I've seen your SS. I would post a "help with dosing" thread so people will look at your ss and see what they think. Advice I can give is when you get a low PS number, you should hold the food and retest in 20-30 minutes to see if he's coming up. If you feed then the number you get is food influenced and doesn't tell much. If he's not shootable regularly at PS then insulin dose may be too high, or you're getting some P action in there, or both.
