Describe what you see on your first 10 clicks

I see two columns. One column has the total times pased and the second column has the time elapsed between each time I clicked the buttons.

Your average time interval for 20 time intervals

0.160935

I took the total final time elapsed and substracted the initial time and then divided this result by twenty. 168.1875-164.9688 = 3.2187/20 = 0.160935

Your general comment to this point

Why did you observe only certain time intervals?

The timer program may only be able to get the closest set range of time elapsed and not an actual time when the range is this low.

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

This tells us that the timer program is able to distinguish between very small time intervals.

Your time intervals for 7 complete breaths:

2.375

Your general comment to this point:

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

The body is not regulated to that degree of specificity and many different factors can change the outcome of your breathing rate. Also, the reaction time between your realizing you are going to inhale and you clicking the mouse is not constant.

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

I think the timer program can predict the events accurately to within about 0.0001 second because the intervals go further than that in specificity and yet the timer program distinguishes between them.

Is the fact that with times in the range from about .12 to over .2 seconds, only a handful of actual intervals were observed, consistent with this conclusion?

My computer is extremely slow tonight so that increased my time.
