Your average time interval for 20 time intervals

.1439285714 I added all the numbers together and divided by the 21 intervals.

Your frequency distribution for the 20 time intervals (interval, number of times it was observed)

.1875, 1

.125, 1

.140625, 3

.15625, 7

.171875, 6

.09375, 1

.015625, 1

Your general comment to this point

Why did you observe only certain time intervals?

I think it rounded to to the nearest interger ending in 5. It doesn't mean the timer is flawed, but that there is a rounded number for each outcome to be able to have a higher chance at frequency.

What did you see when you looked at the differences between time successive time intervals?

i see that there are only 3 numbers used to show the difference and that this must mean there is a limited amount of numbers used in the TIMER program.

Your time intervals for 7 complete breaths:

Your general comment to this point:

Why did you rarely, if ever, observe that same time interval twice?

because the interval was a faster in the first one the numbers were smaller and had limited numbers in the TIMER program, but the larger numbers were able to vary more.

Do you think this program is accurate to .1 or .01 ...

I think statement a. is the most accurate, some of the numbers do not come out to the .01 of a number.
