Your general comment to this point

Why did you observe only certain time intervals?

I think htat the timer rounds and that the tendancy of the repeating numbers is due to the rhytmn of hte clicking of the mouse. There is a time delay from the initial clicking of the mouse and the actual time recorded.

What did you see when you looked at the differences between time successive time intervals?

There is a pattern with the difference also.

Your general comment to this point:

I take a more relaxed breath as i went on.

Why did you rarely, if ever, observe that same time interval twice?

It is probably because we weren't focusing so hard on the clicking and more relaxed.

Do you think this program is accurate to .1 or .01 ...

I say b because the numbers are differant in each interval to that number.
