** Your general comment to this point **
** Why did you observe only certain time intervals? **
I think the program either rounds the intervals up or down
** What did you see when you looked at the differences between time successive time intervals? **
the program appears to be registering numbers in .015 sec intervals
** Your time intervals for 7 complete breaths: **
2.773438

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
I think the program is only accurate to a certain nth of a second
** Do you think this program is accurate to .1 or .01 ... **
b : it appears that the last four digits from my data is repeated 3 times
** Copy of a few lines of your spreadsheet from the TIMER program. **
unable to copy and paste data
