** Your average time interval for 20 time intervals **
.162695
59.46484 - 56.21094 = 3.2539
3.2539 / 20 = .162695

** Your general comment to this point **
** Why did you observe only certain time intervals? **
the program appears to either round up or down
** What did you see when you looked at the differences between time successive time intervals? **
the third column represents the difference between two time intervals
** Your time intervals for 7 complete breaths: **
5.757813

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
the faster we click the more we ask of the program. It appears to be accurate to the .01 second. By slowing our clicks down we are certain to get 10 unique times
** Do you think this program is accurate to .1 or .01 ... **
I think b. is right
