measurement systems evaluation

[dichroic]

So…. my blood pressure was 177/88 last Friday, 122/80 Monday, 144/82 today. I believe I have identified one component of the variation (other than the obvious one, that work in general seems to raise my BP).

I realized today that since with their system they have to read the numbers off a big round analog dial,
It looks like the humans who take the measurements are biased toward double numbers. With as fast as the needle moves, I doubt there’s much visible difference between, say, 144 or 145.

This is what happens when you send someone whose whole job is based around data and evidence to see the doctor!

Wow, I'm surprised they haven't gone over to digital readouts. Maybe those have issues that I'm not aware of.

I'm sorry work is doing that to your blood pressure, but the information is good to have, I hope.
