** Your General Comment **
this online concept is taking me awhile to feel comfortable with this format and program. I may be a little behind but will catch up

** Your general comment to this point **
no comments
** Why did you observe only certain time intervals? **
the timer prgram rounded to the nearest 4 figures. no, the the timer is not flawed. maybe anytime smaller than 4 significant figures is too miniscule
** What did you see when you looked at the differences between time successive time intervals? **
aome differences are in the negative and some are smaller than 4 significant numbers.
** Your time intervals for 7 complete breaths: **
7.203125
6.921875
7.640625
6.796875
9.46875
8.65625
9.015625
8.9375
7.90625
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
the variablility between the time intervals is affected in breathing by voluntary input i.e. anticipation, body position, while repetitive movements have less voluntary input--almost becomes reflexive
** Do you think this program is accurate to .1 or .01 ... **
the timer program is capable of determining the time within about .0001 second
