on the 19th when we tried 3.6u, it looks like he had a slight bounce in the AM and a very late low number at PMPS. This may be a similar thing today so you might want to try to get some later readings to see. Try to get a +11, at minimum. He may drop later today.
Klinger is definitely responding to micro changes. To try to keep him from bouncing so much, which can't feel great, how do you feel about a sliding scale trial this week? Give him 3.5u when he starts out high, and a tiny bit less when he has a lower ps. For example you could try something like:
over 500 3.6u
400-500 3.5u
350-400 3.4u
300-350 3.2u
250-300 2.6u
Obviously these are suggestions only, and the details of the moment will influence it (like how's he acting, eating, is anybody going to be home to test/watch, overnight vs daytime, vomiting etc) Many cats seem to drop lower at night. I don't know why.
I think shooting 3.5u on the 306 was a little risky especially overnight, when we saw that 3.5u dropped him 270 pts on a recent cycle. See what I mean? I know this is confusing, and you should be proud of yourself for trying sooo hard-

keep it up - he's not one of the "easy ones" but you are really helping soo much by gathering the data- without it we really would have nooo clue what was going on. ohmygod_smile GOOD JOB!
