Averages

[Lloyd]

For the last 18 days, my pump shows an average glucose of 96 and a SD of 15. The values were entered from my onetouch meter. 5.5 tests a day average.

For 18 days of data, my navigator shows an average of 91 and a SD of 17. The navigator uses freestyle strips to calibrate.

I think this shows that averages and Standard deviations, derived from 5.5 tests a day are really pretty valid.

Note that this 18 day period coincides with my walking 5 miles a day for about 13 of those days. Managing glucose during that time was pretty hard, the navigator was a big help.

SD during the walks is likely about 30 :)

I have been tweaking my basals, my readings at night have been REALLY good, so the navigator picks up on that.

You have outstandingly good control Lloyd! Keep up the great work.

How big of a role does SD play? Can big swings like 55-175 be dangerous and hazardous to health?

[Lloyd]

There is evidence that variability in glucose, in itself, is a risk (apart from the average).

If you think about it, a non-diabetic does not go as low as 55 or as high as 175. And a non diabetic recovers from whatever peak they may have after a meal, very quickly!

Sd is a measure that shows the highs and lows, a way to measure how much, how long, and how often they happen.

Is it as important as average? I think not. Is it important? I think so.
