I am T2 and over the years I went from low GI diet and exercise through to 3 x 30 units of Nova rapid per day + 1 x 40 units of Lantus per day = Total 130 units I determined my own dosage
In between I was on mixed slow and fast.
and now with no major carbs diet I am just on 4 metaformin tabs once per day.
For 28 years I was an engineer specializing in Instrumentation and Process Control of mega factories. Yes lab instruments and process instruments can be different, and yes all processes can have uncontrolled variables.
I don't want to give you a lecture on how it all fits together but these things are important
In industry we have.
- a set point (desired value) that you aim for.
- alarms called annunciators (flashing lights and sirens) that tell you when you have exceeded an acceptable error
- You have trips that start shutting down the plant to ensure safety.
That is why I suggested the numbers are not important and green and blue and red zones are important
When it comes to auto control there are a few options
a) is called proportional i,e how far off set point determines how much correction
b) is as above but more is added or taken away depending how long it has been off set point
c) is the two above with a speed of change adjustment added.
These three are adjusted until the system cycles (hunts) and goes too hi then too lo then too high etc.
When it hunts it is backed of a bit so it wanders within acceptable limits.
For us lows are bad news and highs + time is bad news so we need to err on the high side.
Computer control on cars is different again and they use factory settings plus what is called INTEGRAL GAP Control but I will not bore you with the detail but what is worth knowing is
If your car will not start you can disconnect the battery negative for 15 minutes the computer will go back to factory settings and will probably start for you. It is like turning your PC off and on at home when it gets all confused.
So back to the meters the numbers only do half a job.
We have to decide what the zones are call them what you like
a) Good 4 - 7 maybe or 5 to 8
b) Iffy 7 -9
c) Dangerous above 10 and below 4
It is up to you where you zone it but the other factors are if you are driving or using machinery you might like to go a little higher because a low could cause death or injury if you pass out.
So back to square 1, 11,3 and 15.6 are both in the red zone.
