I don't understand why some people are allergic to numbers and measurements. You can't construct much of anything without taking some measurements somewhere. This allergy to measurements is about as anti-intellectual and counterproductive as you can get.+1
If it doesn't measure well, I keep working on the circuit.
I've been able to measure effects of fuses and power cords, which has often put me at odds with some that make apocryphal claims about them, but also those that I usually regard as 'objectivists' that won't take anything seriously without good measurements. In the latter case, they don't seem to want to cause their hand to move and make the measurements, instead proclaiming that a fuse or power cord can't make a difference. Without the measurements, their proclamations seem to me as bad (and for the same reason) as those that make the apocryphal claims.
