I'm reminded when I asked an instructor about 'why bother to do exact
calculations for resistance and/or capacitance if the manufacturers
don't make, for example, a 54.5kOhm resistor, or a 51uf capacitor?"

He said "Ah, Geoff!  Welcome to the wonderful world of Electronics!  The
Exacting Science of Approximation!"

Gotta say... he's got a point!

It falls right in line with what I always say: "Measure with a micrometer, 
mark with a chalk line, cut with an axe!"
