Describe what you see on your first 10 clicks
I see a list of numbers, listed at 1 - 10, with numbers ranging from 144.3516 to 151.5859 beside each, respectively, and another column of numbers next to them starting with the same 144.3516, but each after is a number less than 1.

Your average time interval for 20 time intervals

I don't know the easier way so added the 20 and divided by 20.

Your general comment to this point
Why did you observe only certain time intervals?
The timer is useful even if not absolutely accurate. There could be an extremely brief lag in mouse-click-response time and the timer is rounding to a fairly reasonable approximation of how fast the timer can respond to the clicker.
What did you see when you looked at the differences between time successive time intervals?
The timer repeatedly uses the same increments as interval steps. This tells me the timer has a limited amount of intervals for timed increments.
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?
There's a longer time span between fast clicks and relaxed breathing. Even if the clock is timing at specific intervals, these intervals will add up to different amounts given longer time spans.
Do you think this program is accurate to .1 or .01 ...

Copy of a few lines of your spreadsheet from the TIMER program.
The regular timer would not work for me. I was only able to open the won't file timer, therefore,I can only copy and paste. This method does not separate columns but puts all 3 columns into one column.
You have good data and very good answers to questions.
After the due date we will be discussing this experiment further via an online forum.
Either TIMER program will work, and will give you the same information. If only 'won't file' version works it could be that you don't have the c:\vhmthphy folder on the computer you were using; however since you can copy and paste, filing is usually no big deal.
