Hi Sue and Samwise! I've been looking at your spreadsheet and you have got a wide array of numbers there! I know I may seem like a broken record (been saying the same thing to others in PZI land today) but I would gander to say the dose is too high for Samwise right now. Those high preshots flanked by green are major bounces. The lovely thing about PZI vs. the Ls is that you can reduce the dose to try to level out the bounces. Zooming up that much is hard on kitty systems. I know the nadirs are very nice and pretty but going from over 600 to low 100s is way too much of a drop. They only way to get rid of those bounces is to let the cycle even out a little more by dropping back the dose. Once kitty is used to those numbers, then you can slowly increase in an effort to bring the overall numbers down. It looks like in the beginning you held at 1u/0.5u for a while and then quickly went up to 2u. At 2u you started getting shallower curves and then hit greens all of a sudden, which he definitely bounced from. In light of that, I'd recommend going back down to 1.5u BID and test for ketones just to be sure. Give that at least 5 days to let it settle in since it will be a big change in dose. I'd be very curious if they cycles would even out with that change.
