XSS ratio exposure (low, high, peak) is a planned feature in the near future and is being discussed here.
What should be avoided though is thinking we should concentrate on riding in one bucket or another since distribution is spread amongst all three. Even a peak effort contributes a portion of XSS to high and low strain.
So rather than “fill the buckets” individually as I allude to in my mockups, the real goal is to fill them in proportion to your goals for the day (difficulty, focus. XSS ratio).
For example, Easy Pure Endurance (mostly blue) versus Hard Mixed Rouleur (blue. orange, red).
