Your general comment to this point
Why did you observe only certain time intervals?
no it has to round somewhere
What did you see when you looked at the differences between time successive time intervals?
it looks like it's based of multiples of 5 it look like 5^-6 is the smallest increment of time it can recorded

Your general comment to this point:
Why did you rarely, if ever, observe that same time interval twice?
the more time that passes the more accurate the program is.
Do you think this program is accurate to .1 or .01 ...
d
Based on the result of the experiment the timer is accurate to .001 sec but you need one more sec .0001 for rounding and truncation.
