BRM automatically keeps track of each bike’s usage and each night calculates the ‘service points’ for each bike. A simple battery icon  is used to help visualise this metaphor:

full battery = recent servicing

low battery = lots of usage (relative to servicing)

A bike with 100 service points has a full battery, and a bike with 50 service points shows a half-full battery, and so on. This calculation is based on two factors: how much it’s been used since its last service, and the elapsed time since its last service. Each bike is given 100 service points after every service, and the service points are recalculated for each bike, every night, based on the above-mentioned factors and the two parameters you set: dUss – rate at which its USAGE runs down the battery – e.g. if you set to 10, then 10% of its service points are depleted for each day’s usage (default is 25%), and dEss – rate at which ELAPSED time runs down the battery – e.g. if you set to 1, then 1% of its service points are depleted for each day the bike is sitting around between services (default is 1%). The two factors can operate at the same time.

For example a bike that was serviced 9 days ago, and used for 2 days will lose service points based on its USAGE and ELAPSED time. You can set the DUSS and DESS factors in your settings, but if you don’t set them, they will default to 25% and 1% respectively:

changing your default settings:

system -> settings -> system preferences

If you hover your mouse over a battery, you'll see detail of the Duss and Dess:


Of course the service points and associated battery icon are just a quick guide to help you know quickly the ‘readiness’ of your bikes. It does not replace service schedules.

Each time you do a service on your bike, the mechanic can record the work done, and this is maintained as a service history for each bike.
