trackguide with grading

[durandom]

As a driver, I want to see my progress in learning a track.

1. laptime improves
2. time in segment improves
3. a score specific to segment features

Segment features are

1. Brakepoint
2. Brake pressure
3. Gear
4. Turn in
5. Race line
6. Apex

The TrackGuide message holds all notes, which are being evaluated at every entry of the segment. Then the most suitable note is chosen.

Factors are rating of the note (how well did the driver score) and how often the note has been played already and a weight/priority of the note.
