• What is the shortest time interval you think you would be able to measure with reasonable accuracy?

answer/question/discussion (start in the next line):

The shortest time interval I think I could measure with accuracy would be 1s.

• How does the percent error in timing intervals change as the time between the events gets smaller?

answer/question/discussion (start in the next line):

The smaller the intervals, the quicker one has to react to the timer.
