These are objective tests for the quality of the circuit that has been 
produced. They don't say anything about the process that lead to the 
selection of that particular circuit.

If you can't say why you did something in a particular way - and you 
never do - you can't claim to have designed it.

Inspired designers may sometimes get things right first time. Most 
designers rip up any number of first tries at a design before coming up 
with an approach that can be made to work reasonably well. You don't 
tell us about your false starts.

Sometimes those those false starts can become practical when the 
technology moves on - I thought up one scheme in 1976 which didn't 
become practical until 1993 (when I got my hands on a big-enough cheap 
programmable logic device) and it shows up in my 1996 milli-degree 
thermostat paper (section 2.6).
