Did he get R in the evening? I don't see it on the SS.
One of my problems with sorting out the R response is that when Oberon was stuck in the 300s he'd have fluctuations within that range that were sort of random. So the R effect was overlaid on top of that messiness. It meant that sometimes I'd give R and it looked like it didn't do anything, and other times I'd give the same dose and he'd drop 100 points. Eventually we determined that a dose of 1.25 U dropped him about 100 points, so I could give that safely if he was over 300. We later added in other doses for other BGs (1.5 U if over 450; 1 U if between 250 and 300). That's his R scale- it tells me what dose of R I can safely give for a particular preshot BG number. So he might get 1.5 U of R in one cycle, and 1.0 in the next, depending on his BG. Now that the IAA is breaking and he's sliding down the Lantus dosing scale, I'm having to revise the R scale as well, since he's more sensitive to insulin now. Starting over by testing 0.25 U again. Your R scale will likely be different than mine, but this gives you an idea of what to expect. It's a very different approach from the Lantus dosing, where you continually increase the dose until you get to one that's effective (and then drop when reductions are earned).
