** Your general comment to this point **
** Why did you observe only certain time intervals? **
If they are not truly accurate, then yes it must be flawed.
** What did you see when you looked at the differences between time successive time intervals? **
It's the variation from time interval to time interval.

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
Longer intervals leaves more opportunity for variation. It also as more variables.
** Do you think this program is accurate to .1 or .01 ... **
c. The actual time recorded only reads to three decimal places.
** Copy of a few lines of your spreadsheet from the TIMER program. **
