Bought any resistors or capacitors lately? Resistors are commonly sold
with nominal values +/- 20%; capacitors, with +100/-50%. +/-15% may not
be high precision, but it's better than common precision .

And anyway, 35 isn't a whole 15% less than 40, it's only 12.5% less, if
we're going to try for highest arithmetic precision here . No big deal.

If I bought a precision resistor, and it was off by 15%, I'd be upset.

Precision is what you pay for in a resistor. A lot.


1% tolerance resistors are dirt cheap nowadays.

The last 0.1% ones didn't cost that much either.
