** #$&*Your average time interval for 20 time intervals **
.2179
I got this by adding all 20 and dividing the total by 20.
You could also have subtracted clock times and divided by the number of intervals.
Note that you had 20 clock times but only 19 intervals.

** #$&*Your general comment to this point **
** #$&*Why did you observe only certain time intervals? **
It does not mean that the TIMER program is useless but i'm guessing that the program has this time as a rounded figure or something along that line.
** #$&*What did you see when you looked at the differences between time successive time intervals? **
The numbers are very similar and the same in some cases. This shows that the TIMER program may round to these given numbers. Or that that is the fastest the TIMER program can pick up a click.
** #$&*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 with the earlier repetitive clicks you had a certain rhythm with would cause the same time intervals to record. This time however, there was not a certain pattern to your breathing, it was more sporadic.
** #$&*Do you think this program is accurate to .1 or .01 ... **
I would say it is capable of determining the time between two events to within at least about .01 seconds. More practice would be needed to make a better estimate. However, with the given data it seems that .01 is a reasonable answer.
** #$&*Copy of a few lines of your spreadsheet from the TIMER program. **
I could not complete this step because I could not get my TIMER.ete program to work.

20 min, but I wasn't able to do the last step.

I could not get the link for the TIMER.exe program to work. Every time I tried it would say the system cannot find the path specified. So I had to use the other web program. Is there anything else I could try to get the program to work?
If you run the qa_prelim as should be indicated in the instructions, it will create the necessary folder on your hard drive. Or you can create it yourself. The folder you need is c:\vhmthphy and can easily be created on most systems.
