What units and scales do health and enrichment scores use?

Provider scores (activity, sleep, recovery) are unit-less values on a 1-100 scale, calculated by the providers themselves, so 'good' can differ between brands.

Data-enrichment scores are Terra's standardisation across devices, also 0-100, with two exceptions:

• Immunity index: a 0-5 scale, where closer to 5 means the immune system is more likely compromised.

• total_stress_score: higher means more accumulated physiological stress.
