Your general comment to this point
ok
Why did you observe only certain time intervals?
The program is not useless. It gives a relatively close time to what it actually is. The program is done by clicking a button, which then has to send a signal which take a little bit of time which can cause the times to be repeated.
What did you see when you looked at the differences between time successive time intervals?
The difference in the numbers is not very large at all. It is pretty much random in that it took less or more time to click on the button. The timer program is consistent because the difference between each interval different but not by a large amount.

Your general comment to this point:
ok
Why did you rarely, if ever, observe that same time interval twice?
When you breath the fluctuate. When you are just repetitively clicking it is easier to be more consistent.
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 .0001 second. I think this because the numbers go to the ten thousandth place which means that the last number is rounded.
Copy of a few lines of your spreadsheet from the TIMER program.
event number clock time time interval
1 2.015625 2.015625
2 2.234375 0.21875
3 2.390625 0.15625

Good.
