step function system response - overview

1514 step function tests were done.
the system response was monitored each time.
For 93% of the tests, the system response was as expected.
(do not confuse "as expected" with "ideal" or "best".)
For 7% of the tests the system response was not as expected, being much much too slow and taking way too long thereafter to completely come up to speed.

Note: The y-axis of these graphs is now "gap-time" instead of CPU frequency. This was not done to confuse the reader, but the reverse frequency calculation was not done on purpose. It is preferable to observe the data in units of time, without introducing frequency errors due to ISR and other latency gaps. Approximate CPU frequency conversions have been added.

While I will post about 5 graphs for this experiment, I have hundreds and have done many different EPPs and on and on ...
