How it works?

First, RChrono is a standard chronometer with 30 lap's capacity. The interesting feature is the final time calculation.

An example of use is better than a long description.

You want to run a marathon. In the setting menu, you set 42.2 for the final distance. At the beginning of the race you start the chronometer. Commonly on a marathon you have label each 5km. At each label, you press the lap button, you enter the distance and the watch will estimate the final time. The final time will be updated each you time you enter a new distance.

In order to calculate the final time, the program calculates your average speed and estimate the final time assuming that you will continue to run at the same speed. Simple…

The Auto-distance feature allows the program to automatically add an amount of distance at each lap. For example, if you set 5 the program will add 5 to the distance each time you press the lap button. You will have just to validate the distance (or you can modify the distance).
