Your General Comment

Describe what you see on your first 10 clicks

0 - 10 in the first column then numbers in the ninties after that and around .35s in the 3rd column

Your average time interval for 20 time intervals

.15327

I just added all the numbers together and divided by 21 since there isn't an interval for the first number

Your general comment to this point

Why did you observe only certain time intervals?

It might be as fast as the program can process the clicks, so it reports those numbers, while you might actually be moving faster. It's not useless or flawed its still fairly accurate.

What did you see when you looked at the differences between time successive time intervals?

the program can only process at a certain speed, its limited by the efficiency in its programming to how fast it can run

Your general comment to this point:

Why did you rarely, if ever, observe that same time interval twice?

the button wasn't being clicked so fast that the program was moving at the fastest possible speed so it was able to report the numbers with more accuracy

Do you think this program is accurate to .1 or .01 ...

A. the closest it seems the program can get is .015 and since it can't measure down to .01 the most accurate answer is .1
