** Your general comment to this point **

** Why did you observe only certain time intervals? **

i would guess that it estimates it to make it more easy for us to calculate.

** What did you see when you looked at the differences between time successive time intervals? **

this shows you the variation between the time intervals, if it incresed it shows it as a positive number, and if it decreases it shows it as a negative number.

** Your time intervals for 7 complete breaths: **

** Your general comment to this point: **

** Why did you rarely, if ever, observe that same time interval twice? **

because the numbers were greater, less estimation was needed.

** Do you think this program is accurate to .1 or .01 ... **

b. The TIMER program is capable of determining the time between two events accurately to within about .01 second.

** Copy of a few lines of your spreadsheet from the TIMER program. **
