** Describe what you see on your first 10 clicks **
It gives you the number 1 and the initial time. Then it gives you the number two, the second time, and difference between time one and time two. Then it gives the number three, the third time, and then the difference between time two and three. It continues like this through the number ten.

** #$&*Your average time interval for 20 time intervals **
.164844, I added all of them and then divided by 20 bc I didn't know any other way to do it.
** #$&*Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.140625, 2
.15625, 3
.171875, 9
.1875, 3
.203125, 1
.234375, 1
** #$&*Your general comment to this point **
** #$&*Why did you observe only certain time intervals? **
It probably rounds to specific numbers and no this wouldn't make it useless. It still gives a fairly accurate number.
** #$&*What did you see when you looked at the differences between time successive time intervals? **
It uses a lot of the same numbers. It seems to round to certain numbers, maybe its setup to use certain intervals.
** #$&*Your time intervals for 7 complete breaths: **
4.671875
4.453125
4.703125
4.046875
3.953125
4.093275
4.171875
3.875
4.46875
** #$&*Your general comment to this point: **
These intervals are widely different.
** #$&*Why did you rarely, if ever, observe that same time interval twice? **
Because there is a lot of time difference between each breath. It the rapid pushing of the timer button, it wasn't much time difference at all.
** #$&*Do you think this program is accurate to .1 or .01 ... **
b because on the shorter time intervals that was about as close as it could get.
