[Amps] parasitic suppressor voodoo

[Dave White]

Maybe another reason that we don't see too many worked-through rigorous calculations is that there are so many variables in play and since parasitics result from positive feedback the smallest variation in the values of the large numbers of seemingly insignificant factors can cause huge variations in the system behaviour down the line. The sheer randomness of many factors also comes into play.

Do a bit of Googling about Chaos Theory versus deterministic predictability and you'll see what I mean.  Chaos is a fundamentaly different way of looking at a problem.  It has many applications from meteorology to Agile software development, business planning and ..... who knows .... maybe parasitic suppressors :-)
