** Your average time interval for 20 time intervals **
0.168690789
I added up all the intervals, except the first which was the start time, and then divided by 19 to compensate for this.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.140625
.15625, 9

** Your general comment to this point **
** Why did you observe only certain time intervals? **
No, the timer program just has specifically programmed intervals in order to be able to account for such small time intervals.
** What did you see when you looked at the differences between time successive time intervals? **
This tells me that the timer program has specific time intervals programmed into it, for every .01563 seconds.

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
This is what we would expect becuase now we are using much larger time intervals, and are not trying to calculate intervals small enough to be close to those specifically coded into the timer.
** Do you think this program is accurate to .1 or .01 ... **
The TIMER program is capable of determining the time between two events accurately to within about .01 second.
This is because the interval between the clicks was approximately .01; more accurately .01563
