** Your average time interval for 20 time intervals **
I got .2551172
I added the first 20 and divided by 20 to get the average.

** Your general comment to this point **
** Why did you observe only certain time intervals? **
Im not sure. Would it be because of you being consistent? I dont believe the timer is useless but there may be a flaw in how it perceives your click and the time it takes to rate it.
** What did you see when you looked at the differences between time successive time intervals? **
.03125 is repeated 3 times and .015625 is repeated 2 times but it is just .000025 off of .01563 and that number is repeated 4 times
** Your time intervals for 7 complete breaths: **
2710.945

** Your general comment to this point: **
I am suffering with bronchitis right now and have been for 2 weeks so I would actually enjoy being able to sleep. I have almost forgotten what relaxed breathing is.
** Why did you rarely, if ever, observe that same time interval twice? **
When you relax the interval would be longer. No one takes breaths with the same intervals especially if you are trying to time it. When I worked at the hospital we were told to count respirations while doing something else like pulse so the patient wouldn't know that we were counting.
** Do you think this program is accurate to .1 or .01 ... **
I believe that it is accurate to about .1 second because if you look at my numbers and round the tenths it would be almost the same time between breaths.

about an hour and a half but I had several interruptions

When I was using the timer I hit the wrong button and lost my first set of data for the breaths so I did another one that is why the numbers are different. Also I dont have excel for the spreadsheet on my computer. I have Microsoft and it was not set up like you explained. I dont know if I set it right to be comma-delimited. There were no options like that to choose from. The information just showed up when I hit browse and chose the title.
