I have two HV voltage dividers, each composed of 8x499kOhm+10kOhm resistors.
Made of 0.1% resistors, because why not. That should result in 4.002MOhm
end to end, in the range 3998..4006Ohms. A bit better, if the
distributions are assumed to be Gaussian and added properly. But hey,
not *that*:

Since -- as they say -- there no accidents, just signs, what's
the sign here? Have the factories been seized by six-sigma aliens and
the lines silently switched to 0.01%? And they continue to sell "just"
0.1% because the market demands so? The meter is good, but not that
good, either.
Needless to say the other divider provides exactly the same, rock-stable
reading.
Best regards, Piotr
