AMPS = 399 (2.8u) :shock:
+1 = 450
+4 = 200 :shock:
+6 = 213
PMPS = 241 (2.4u)
+3 = 176
+4 = 144
+5 = 113
+6 = 75 :mrgreen:
+7 = 73 :mrgreen:


Where did that AMPS come from? Would likely have shot higher if I could monitor today. Last night's cycle was mediocre, but yesterday's AM cycle was good.

I think I found a problem with doing sliding scale, though, and I'm chewing on an idea for dealing with it. Eddie likes to surf sometimes, so his PS isn't necessarily always reflective of his "peak", and the bigger the drop on the cycle, the bigger the rise at the end of the cycle. The upside is that he doesn't have to sit in high numbers for hours until the onset of the next shot so he sort of gets some overlap, but the downside is that the insulin is trying to play catch up with the rise, and dosing based on the pre-shot doesn't factor in how high he will be at peak.

Last night for example, he had a beautiful PMPS of 197, but I was 99% sure he would rise pretty dramatically from there since he had a pretty low nadir during the AM cycle. I didn't test a +2, but I'm guessing he probably was in the 300's at peak before slowly coming down. For a peak of 300 clearly 2.0u is not enough. I almost shot higher than 2.0 but chickened out since that's the lowest PS we've shot. Assuming he had a peak somewhere in the 300's, the nadir (if it wasn't later than +6), was still a fairly steep drop, hence the high AMPS this morning, unless it's a bounce or some other randomness.

In contrast, on the AMPS of 2/3, the pre-shot of 246 was probably fairly accurate in terms of the peak of his cycle, and he probably didn't rise much after that, since the cycle before that was relatively flat, so the 2.4u did the job like it was supposed to, and he had a good cycle that AM.

I think I can actually see this pattern pretty consistently, and that's why we'd have a good cycle, followed by what appeared to be a flat yellow cycle. Without testing early in the cycle, I wasn't catching how high he was actually rising after his pre-shot reading.

The gist of it is, I'm going to almost invariably be underdosing on the sliding scale on the pre-shot following a good cycle where there's a fairly steep curve, because Eddie's still rising pretty rapidly after pre-shot until the onset of the next dose. So we get a good cycle, followed by a flat cycle, followed by a good cycle, and so forth. Assuming I'm correct on this, and assuming Eddie's following this pattern more often than not, if I can guesstimate how high his peak will be after a good cycle while he's still on the rise, I can dose a higher amount to account for his peak.

The downside is, that if I'm wrong about seeing a pattern to this, and overestimate how high he's going to go, I may end up dosing too much. That said, my scale doesn't have huge variances, so a dose that's higher than necessary isn't going to likely send him way low. I think I'd only try this out in the PM cycles to test this when I can monitor, but it makes dosing on the scale, since I'd be dosing based on his anticipated peak, rather than the actual PS number more complicated. That said, if I can accomplish this, it might help get better cycles more often and stop the swinging back and forth between a good cycle followed by a not so good cycle, and back and forth.

Sorry for the novel. I'm trying to get my thought process down as much as anything here. Maybe I'm adding in too many variables.

Hope everyone has a wonderful day today!
 
Re: 2/4 Eddie AMPS 399

Yeah this morning's AMPS looks like one of two things. Either a bounce or a fur shot last night.
I don't see a number that would have caused a bounce, but he might have had a late nadir last night for some odd reason. Any chance some of the shot "missed" last night?

As for the increase after AMPS or PMPS, that isn't abnormal. There should be some rise due to eating within the first hour or two and then the insulin should be reaching onset and start pushing the numbers back down. As far as anticipating that rise, the possible issue with that is "what happens if he decides to barf up his meal?" In that case, the rise is most likely not going to happen.

If you are trying to see the "rate of rise" at shot time, you could test at +11 and compare that to the PS reading, which leaves food out of the equation.
 
Re: 2/4 Eddie AMPS 399

Thanks Carl. I'm thinking it's something I ought to try to get more data on before messing with things too much.

I think what happened was that he had a low 100 or even a high green in between the +5.5 and +9 yesterday during the AM cycle, and that he did actually probably climb a bit higher after his nice PMPS number, and the 2u was just enough bring him off a 300+, which is one of those "invisible numbers." So in essence, it may have been enough to suppress a bounce, but not enough to really bring him down. So then this AM was the bounce let loose. Or something like that.

It does look like this AMPS and the +1 were a wicked little bounce which he cleared immediately. This science-oriented bean trusted her instinct and ran out for an "errand" at just shy of +4 and he's at 200. :o Fed 2 Tbsp. FF and left out a popsicle to try to slow him down a bit so I'm not trying to bring him back up over lunch hour. 250+ point drop in 3 hours is a little fast and steep in my mind. :shock: Or maybe he'll just cruise in the low yellows and high blues today. No idea what to expect out of this cycle.
