Just looking at the last couple of days, I was thinking "earlier". Like what if the nadir was a bit less than 87 and the 310 was a mini-bounce? But also that night, if the nadir was earlier than +6, then the 367 might be a bounce off that...
But then if I look back a few more days, that logic doesn't seem to make sense either? Unless he just doesn't have a consistent nadir? I know that in the study I looked at when they were testing Prozinc against the old PZI, the data seemed to suggest that the longer a kitty was on Prozinc, the later the nadir. But then that study only lasted 45 days.
