Ideal range and tiers
Each value falls into a tier (T1 = ideal). Comfortably inside T1 the rating is 10, easing to 9.5 at the edges of the ideal range; beyond it the rating falls with the deviation — fastest in the first tiers outside the ideal — down to −10 (below 0 where the original tier sheet takes points away) at the far end of the worst tier.
| Tier | Range | Rating |
|---|---|---|
| T1 Ideal | 125–132° | 9.5–10 |
| T2 Near ideal | 120–125° | 7.2–9.5 |
| T3 Mild deviation | 118–120° or 132–135° | 5.2–7.2 |
| T4 Moderate deviation | 116–118° or 135–138° | 3.4–5.2 |
| T5 Significant deviation | 114–116° or 138–141° | −5 to 3.4 |
| T6 Severe deviation | < 114° or > 141° | −10 to −5 |
