Describe what you see on your first 10 clicks

I see 2 columns of numbers. The first set is the time of each time I pressed the click to time event button. The 2nd column is the seconds in between each time I clicked the time event button.

Your general comment to this point

Why did you observe only certain time intervals?

Maybe the time is rounding up. I don' think it is flawed and can still be useful.

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

The 3rd column is showing positive and negative numbers. Is that right?

Your time intervals for 7 complete breaths:

2.371094

2.40625

2.691406

2.933594

3.121094

3.742188

4.789063

5.925781

6.582301

Your general comment to this point:

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

Because I was relaxed and it takes time in between breaths.

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