** Your general comment to this point **
** Why did you observe only certain time intervals? **
I think that the timer program has certain numbers that is already programed to. once it hits those numbers it continues to reach allocate them because of the time that we are asking it to produce the next number. It is not able to accurately post the next number without more time
** What did you see when you looked at the differences between time successive time intervals? **
I see that the difference from one time interval to the next is a lot like the time intervals and shows that we were right in taking note that the intervals occurred numerous times.
** Your time intervals for 7 complete breaths: **
834.0273
4.132813
3.925781
2.964844
3.027344
3.199219
3.058594
3.816406
Good, but 834 seconds is not one of the intervals being observed (unlikely that you took that long between breaths).
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
I think this happened because the timer was able to process the clicks more. when the clicks were done in a repeating manner it did not process it accurately.
** Do you think this program is accurate to .1 or .01 ... **
I would say that the timer would be more capable of providing an accurate time when the events are within .01 seconds.

it took approximately 40 minutes from start to finish and I did have some trouble opening the timer application.
