On: Why does the E12 resistor sequence use 27 and 33 instead of 26 and 32?

Nope. Not buying it. Just pulled a couple of bog standard thick film 100K 1% 1206s and they are measuring at 99.94, 99.96, 100.02, 99.93 kiloohms.

They're probably batch controlled. There is no way every resistor is being tested for compliance given how cheap SMT resistors are.
