** Your General Comment **
** Describe what you see on your first 10 clicks **
a list of ten times in seconds. With the times that are listed is the current time's difference from the previous time. Time 1's difference is not available because there is not a previous time.

** Your average time interval for 20 time intervals **
.171875
Although it is not the quicker way I am sure, I copied the data into a spreadsheet and used a formula to determine the answer.
** Your frequency distribution for the 20 time intervals (interval, number of times it was observed) **
.1875,3
.15625,3
.171875,14
** Your general comment to this point **
** Why did you observe only certain time intervals? **
The timer is not useless and it is not necessarily flawed. The program written more than likely uses data banks to pull the interval from.
** What did you see when you looked at the differences between time successive time intervals? **
This shows how the timer program decides which number to display when pulling from a database. If the number is minus then it will display the next number down if it is positive then it will display the next number up. If it is a multiple of .015625 then it will go in the determined direction by the multiple.

** Your general comment to this point: **
** Why did you rarely, if ever, observe that same time interval twice? **
There is more time between breaths that do not allow the program to pull from its data banks in close locations.
** Do you think this program is accurate to .1 or .01 ... **
.01 second. I think this because it is apparent that the timer program uses a data bank or formula in the programming that uses a core of .015625 as its standard of time measurement. If you divide this by 2 because of the fact that the program is rounding up or down from this number then the solution is .0078125. Throw out the significant figures and you are left with a measurement to the hundredth decimal location. I am probably not right but I think that this is a pretty good guess.
