The elapsed stats is probably the most important stat that you should check always. It should be as close to the main timer as possible. Each time you click on the text you will display a new stat. It displays elapsed time, main cycling time, time slowed by and the minimum ham cycle.

For the example above you can see the cycling is slowed by 90ms because it probably received some PRE's. You can take that time away by pressing the reset timer button. If the elapsed time is really high like in the 2000ms area then you should reset it unless you have other scripts running. If you do have other scripts running you might want to use the second timer or third timer which have slower times.
