Well, I'm too late to the party to be much help. Also not sure what time zone you are in & how the times fit together.
In the absense of any other info in general I would say shooting later is safer unless he has ketones. If shooting earlier, one might want to reduce the dose, depending on how early and what kind of #s you are getting. It can really change the effect of the dose because of the overlap. If you end up shooting later, you may want to increase the dose a tiny bit (on the order of 0.2u) for the same reason (in reverse, i.e. loss of overlap), but again it depends on what kind of #s your kitty is getting, etc.
No easy answers here! ;-) Let us know what you ended up with, & how Max is doing!
