** Describe what you see on your first 10 clicks **
There are three columns, one labeled 1-10 and then 2 others (I am guessing they are the start and stop time of the 10 trials)

** Your general comment to this point **
no questions
** Why did you observe only certain time intervals? **
no, it means the computer tends to round that that number.
** What did you see when you looked at the differences between time successive time intervals? **
it shows the variedness from one interval to another, if we could accuratly to the program, it would be zero.
** Your time intervals for 7 complete breaths: **
2.765625
4.214844
3.425781
4.40625
3.367188

3.953125
3.554688
3.464844
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
because breathing is irregular, also because they were farther apart and we were relaxed, they are not as likely to be identical.
** Do you think this program is accurate to .1 or .01 ... **
I think it depends on how apart the intervals are, it the time between intervals is very small then it is fairly accurate, but it the time between events is large, it loses accuracy. so a.
