I just noticed that the 30-day average on my One Touch Ultra never
exceeds n=150, or five tests per day. In fact, it never varies from
n=150. I routinely test 6-8 times or more per day. Why is that not
reflected?

Have you calibrated your meter? Have you tried manually writing down your
results and doing your own average and comparing the results?

It probably bases the average on the last 30 days or 150 readings, whichever
is less.

See page 33 of your manual. Memory meters "throw values away" when the
number of tests exceed the allocated memory slots. Yours only saves 150
readings, then tosses the oldest when a new one appears.

I couldn't find the manual. That's why I asked here. Anyway, the
manual has since turned up and indeed, it only keeps the last 150
readings. Which makes a "30-day average" misleading. According to my
14-day average I'm testing seven times a day, so 150 readings only
reflects about 20 days of testing.

And that 150 readings would be several months for people who follow some
doctors' advice about testing only once or twice a day (or even week)!
