Your 'timer program' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
** Your General Comment **
** Describe what you see on your first 10 clicks **
It gives me a list of ten different times in a left side column and on the right column, I think there is a list of the changes in time from each click.

** Your average time interval for 20 time intervals **
.1371048763
I did it the long way and just added up all twenty and then divided by 20.

** Your general comment to this point **
** Why did you observe only certain time intervals? **
I don't really know if the TIMER program is flawed (maybe it just catches on the same numbers sometimes). I don't think it is useless.
** What did you see when you looked at the differences between time successive time intervals? **
This set also contains many of the same numbers. Maybe the TIMER program is flawed?? No.....
** 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? **
I believe we would expect the same numbers when doing the fast clicks because we are in a high-paced rhythm and when we were doing the breathing, we really didn't have any rhythm and we observed different numbers.
** Do you think this program is accurate to .1 or .01 ... **
I would probably have to go with b because the TIMER program is very accurate, but it only records when we press the button. There is that split second that it takes our minds to process to hit the button and our fingers to actually do it. For that, I think that we can trust that TIMER combined with our human flaws will allow us to possibly record events accurately within about .01 second.
