** Your average time interval for 20 time intervals **
.18828125
&#If you divide the difference between the 1st and 20th time clock times by the 20 - 1 = 19 time intervals you would get the average time interval, and this will agree with the average you obtained by adding the 19 intervals and dividing by 19.
More generally, if you take the difference between two clock times and the difference between their numberings, i.e., subtract the second-column numbers, subtract the first-column numbers and divide, you will get the average of the time intervals between those clock times. &#
i got this by adding up all the first 20 time intervals and dividing the total by 20.

** Your general comment to this point **
** Why did you observe only certain time intervals? **
I guess it means that it is a very accurate program
** What did you see when you looked at the differences between time successive time intervals? **
The numbers repeat themselves frequently , and there is a pattern
** Your time intervals for 7 complete breaths: **
1853.078
5.515625
5
4.96875
4.65625
4.78125
4.453125
4.046875
4.484375
4.109375
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
because there were different times between each breath and so there would be different times in the time intervals.
** Do you think this program is accurate to .1 or .01 ... **
