I'd be interested to know how you verify or test your own perceptions in
this area. In my experience it is one thing to have an impression that a
change has had an effect. It is something else to test this over a
period of time in a way that can reliably rule out uncontrolled
variables or variations in hearing. How do you do this when coming to
your conclusions?

In one. Generally, when you try something, you've got a pre-conceived
guess as to the end result. Relying on your 'ears' to hear that 'change'
is a pointless exercise.
