very quick; good physiology
** Your general comment to this point **
.0078125
** Why did you observe only certain time intervals? **
The program does not get the very exact number but uses an interval of .0078125 and which ever time the button is clicked, it will round based on that number. The program is now flawed; I think it is very accurate being compared to, e.g., a stop watch. The numbers are pretty accurate +/- 0.00390625 seconds. (assuming the clock times are in seconds)
** What did you see when you looked at the differences between time successive time intervals? **
The variation of time intervals; the program is pretty accurate.
** Your time intervals for 7 complete breaths: **
18.08594
22.89063
29.0625
31.70313

** Your general comment to this point: **
Stopped when it seemed I had peaked doing relaxed breathes
** Why did you rarely, if ever, observe that same time interval twice? **
As the lungs keep expanding more and more each time, it becomes easier to take relaxed breathes. Since there are such larger time intervals between the breathes than fast clicks, it is going to be more unlikely that a breathe lasts the exact same amount of time.
** Do you think this program is accurate to .1 or .01 ... **
The most accurate statement is B. From judging from the clicks in the first trial - was able to narrow down the intervals from what I observed.
