** Your General Comment **
** Describe what you see on your first 10 clicks **
I see numbered events with total seconds between each event and a total seconds that each event is clicked on.

** Your general comment to this point **
** Why did you observe only certain time intervals? **
I guess it can only record to a certain degree of accuracy/rounds to a certain degree to obtain similar numbers.
** What did you see when you looked at the differences between time successive time intervals? **
the timer program only reads in .01563 increments.
** Your time intervals for 7 complete breaths: **
5.78125
4.546875
4.546875
4.578125

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
The greater interval between events gives more space for different results.
** Do you think this program is accurate to .1 or .01 ... **
B.
the difference reported between the intervals in the fast clicks above is .015 always, so I assume two decimal places.
