** Your General Comment **
** Describe what you see on your first 10 clicks **
It seems to be counting the time between clicks.

** Your average time interval for 20 time intervals **

I divided the duration of time by 20.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
0.1577148, 1
0.1552734, 1
0.1318359, 1
0.0859375, 1
0.09375, 1
There are 20 time intervals. The information you report here accounts for only five of them. All the intervals need to be accounted for.
** Your general comment to this point **
** Why did you observe only certain time intervals? **
** What did you see when you looked at the differences between time successive time intervals? **
The differnce from one time interval to the next would be our second derivative telling us whether we are speeding up or slowing down with our clicks.
** Your time intervals for 7 complete breaths: **
13.54297
10.24512
10.01074
12.15039
12.60498
11.65869
12.39014
14.96582
14.3042
15.43994
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Well statistically speaking because we didn't have as many numbers, but mainly because of our continuing to relax more and more over the period of time and the intervals becoming longer.
** Do you think this program is accurate to .1 or .01 ... **
c. The TIMER program is capable of determining the time between two events accurately to within about .001 second.
