** Your general comment to this point **
** Why did you observe only certain time intervals? **
It is possible that the program is unable to calculate at the fast speed of a rapid mouse click. This does not mean it is flawed rather it has it's uses within a certain range of speed.
** What did you see when you looked at the differences between time successive time intervals? **
That when the time interval is in the thousanths place, it begins to have error.
** Your time intervals for 7 complete breaths: **
3.078125
3.3125
3.59375

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
The program has a longer time to make calculations thus making it more accurate.
** Do you think this program is accurate to .1 or .01 ... **
C, because even on the slow clicking I began to see numbers repeating after the thousanth place just as I did on the fast clicking.
