** Your average time interval for 20 time intervals **
0.20404
I just took the basic route. I added up the first 20 intervals and divided by 20.

** Your general comment to this point **
It looks like I wasn't as consistent as you.
** Why did you observe only certain time intervals? **
I think that when the values are really close together, the program might round up or down for the sake of not being redundant. I dont think that it makes the program flawed, but just a little easier to work with, since you wont have a whole bunch of similar values.
** What did you see when you looked at the differences between time successive time intervals? **
This tell us how one value compares to the next. So the timer program tells us how accurate we are.
** Your time intervals for 7 complete breaths: **
6.121094
5.666016
7.005859
7.039063
7.081055
7.871094
8.327148
9.243652
8.949219
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
This is because first, as you said when you're taking deep breaths like that, you tend to breathe deeper and deeper each time so the values will vary each time. It's different when you're doing an act rapidly like clicking a mouse.
** Do you think this program is accurate to .1 or .01 ... **
d. within about .0001 second because most of the values are reported to the ten-thousandth (i think) place, or 4 decimal places.
