Your average time interval for 20 time intervals
At 20 overall time was 256.6602 at 1 overall time was 253.1133 if I subtract the 20th time from the first time and divide by 20 I will have my average.
Thus 256.6602 - 253.1133 = 3.5469/20 = .177345 sec

Your general comment to this point
Why did you observe only certain time intervals?
This just means the program has limitations to the accuracy it has at such quick time intervals the program is not useless unless you were needing more exact data for the specific experiment you were doing
What did you see when you looked at the differences between time successive time intervals?
Those numbers have many repetitions as well this suggests that this program is not able to calsulate with great accuracy ver small time intervals

Your general comment to this point:
Why did you rarely, if ever, observe that same time interval twice?
The time intervals are much higher in this exercise so the accuracy of this program increases greatly
Do you think this program is accurate to .1 or .01 ...
