I added the numbers and divided by 20.

** Your general comment to this point **

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

The Timer program reported the clicks. If there is a flaw then it is byt he operator and not the timer program. It is a useful tool.

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

It repeats itself and has an amount of uncertainty in it's calculations just like a stop watch has .2 s of uncertainty.

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

3.53125

3.46875

3.703125

3.71875

3.40625

3.285156

3.109375

3.421875

** Your general comment to this point: **

I think I forgot to hit the button on the second to last one. I was so relaxed.

controlled breathing can do that to you

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

The times were not as constant or consistant since it was a relaxing exercise. With the fast clicks it was more repeating than with the breathing exercises.

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

B. since looking back at your differences between intervals it seems it is accurate with or about .01 s.

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

I had a problem getting the timer.exe file to run, therefore spent more time loading items from the trouble shooting screens.

Very good work.
