How this category is graded

Tier S is top material worth sorting out and keeping separate. Tier A is high value and worth the labour to harvest. Tier B is solid in volume. Tier C only pays at scale or as part of the board it sits on. Tier D is near zero — knowing what not to spend time on is half the skill.
