taking a stab at this:
I am not familiar with "cadd code" If you intended to say "copy code" then yes, I did copy some code in an effort to learn how it works.
I think Steve was saying add code. With that he is pointing out that you have added code overhead but don't use interrupt on the timer, so the added code slows the clock down. Adding the pause is just to illistrate this further.

And all that Bruce said.
