** Your General Comment **
I skipped this section somehow so I am now submitting it.
** Describe what you see on your first 10 clicks **
There are two columns numbered 1-10 with numbers beside them.

** Your average time interval for 20 time intervals **
23.4781266
None of your quick-click intervals exceeds .5 second, and I would be that the .40 second interval corresponds to a missed click.
In any case you certainly didn't have a 465-second interval between quick clicks.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.2851563,1
.265625,1
.1601563,3
.40625,1
.1445313,1
.3125,1
.328125,1
.1835938,2
.1679688,1
.1523438,1
.2734375,1
.2226563,1
.1757813,1
.1914063,1
.5351563,1
.2109375,1
The average of the numbers in this reported distribution is less than .3 second. Certainly not 20+ seconds.
** Your general comment to this point **
The frequency of the answers I have are not as repetitive as the ones above in the example.
** Why did you observe only certain time intervals? **
The timer program may not be flawed there is a difference in reaction times for me.
** What did you see when you looked at the differences between time successive time intervals? **
The difference in the time intervals from one to the other have greater frequency.
** Your time intervals for 7 complete breaths: **
6.539063
6.984375
6.125
7.984375
6.910156
6.199219
6.191406
7.359375
6.441406
** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
As you relax your breathes become less frequent.
** Do you think this program is accurate to .1 or .01 ... **
D. The first four numbers past the decimal are consistent.

When I saved the above information it saved in Notepad instead of Excel. Is this ok?
Notepad is preferable to Excel for most purposes.
In any case the file saves as a text file. Excel will open text files.
