** Your General Comment **

** Describe what you see on your first 10 clicks **

The timer has recorded 10 events. The results are outlined in 3 columns.

The first column displays the event number (1, 2, 3, etc.). The second column displays an event time (e.g. 1034.336). The third column displays the differential of events (e.g. 0.5351563).

It appears to me this timer is setup like a stop watch.

** Your general comment to this point **

** Why did you observe only certain time intervals? **

I think you achieved those intervals. Now...were they exactly controlled or is that just your uncoltrolled speed of clicking the mouse. Comparing your times to mine, I think the timer is working and good.

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

I see a lot of repeat times of 0.1563 along with two additional times of 0.15625 (only a slight difference) that would indicate a lot of repeat times and maybe a flaw in the time. The other none-repeat times are exactly the same at 0.3125 intervals which are almost double the other intervals.

5.015625

** Your general comment to this point: **

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

Because our breathing is slower than our first exercise and we will not be able to click at the exact same point within a breathing cycle to replicate our time.

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