A. You took a correct dose and the timings are slightly out of sync, but BG will eventually turn around.
B. You under-dosed and will need to either take a correction dose, or wait a long time for the basal dose to fix it.
It can at times be very difficult to distinguish between A and B, and guessing wrong has consequences. Futhermore, you won't really know which is the case until sometime later. 1. ... CGM devices had options for more frequent updates during highs and lows. Tighter feedback loops could go a long way.
2. ... pumps could dose insulin and glucagon automatically.
3. ... there were even faster acting insulins. This is tough because most insulins are injected interstitially, which takes time for your body to absorb. Maybe an out-patient implantable pump that could inject intravenously would help?
4. ... there were BETTER INSULIN PUMP SOFTWARE for calculating doses. I have a Tandem T:Slim x2. I can tell it how many carbs I am eating. Only that. It doesn't count or learn from: proteins, fats, what kinds of carbs, or what specific ingredients are there, or their ratios. All of this can dramatically effect how quickly your BG rises, bringing you back to the original problem of guessing. It should be possible to select from a database of commercially available food and manually provided recipes.
As near as I can tell, it is just a different way of deciding how the property tax burden is levied.
Downtown property gets taxed much more. Un-developed speculation property that doesn't contribute to the community (and derives value from other people's contributions) get taxed at the same rate as nearby developed property.
