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 | 12–23° | 9.5–10 |
| T2 Near ideal | 9–12° or 23–26° | 7.2–9.5 |
| T3 Mild deviation | 7–9° or 26–28° | 5.2–7.2 |
| T4 Moderate deviation | 4–7° or 28–31° | 3.4–5.2 |
| T5 Significant deviation | 0–4° or 31–35° | −5 to 3.4 |
| T6 Severe deviation | < 0° or > 35° | −10 to −5 |
| Tier | Range | Rating |
|---|---|---|
| T1 Ideal | 10–19° | 9.5–10 |
| T2 Near ideal | 7–10° or 19–22° | 7.2–9.5 |
| T3 Mild deviation | 5–7° or 22–24° | 5.2–7.2 |
| T4 Moderate deviation | 2–5° or 24–27° | 3.4–5.2 |
| T5 Significant deviation | −2 to 2° or 27–31° | −5 to 3.4 |
