How to track events

I am studing some capacity planning metrics and I am curious on how
should events in a time period should be tracked for use in analysis.

Lets say I have the following:

Week #, Usage, Conversions, ST1 Starts, ST1 Ends, ST2 Starts, ST Ends
1,345,0,1,0,0,0
2,456,0,0,1,0,0
3,234,0,0,0,1,1 //ST2 Starts and ends in the same week
4,567,1,0,0,0,0
5,673,2,0,0,0,0 // There are 2 conversion that week
6,879,0,1,0,1,0 // ST1 and ST2 have started
7,545,0,0,0,0,0 // ST1 and 2 are still running
8,789,2,0,1,0,0 // 2 conversions, ST1 ends, ST2 still going
9,342,0,0,0,0,1 // ST2 ends

The data after Week # and Usage is the output of a crosstab table of a
calendar which I massaged into a weekly sample (I only get weekly data
even though I get the calendar stuff on specific days). As you can see
they only have the start and end times indicated for the system tests.
So this brings me to question #1:

For statistical analysis should I indicate, for running tasks a 1
during all periods that something is running:

e.g.
Week,ST1, ST2
1,1,0 // ST1 starts
2,1,0
3,1,1 // ST1 ends, ST2 Starts
4,0,1
5,0,1 // ST2 ends
6,0,0
7,1,0 //ST1 starts and ends in this week
8,0,0

Or for time series analysis is the start and ends only significant?
