Scale Rule Comparison
| Scaling Rule | Net BF | Value ($) | Characteristics |
|---|---|---|---|
| Doyle | 108 BF | $270.00 | Under-scales small logs, favors buyer |
| Scribner Dec. C | 120 BF | $300.00 | Nearest 10 BF (Tally: 12) |
| Int 1/4" | 135 BF | $337.50 | Most accurate representation for band mills |
| Square Cant | 112 BF | $280.00 | Yield from maximum center timber (cant) |
Scribner Decimal C: $V = (0.79D^2 - 2D - 4) \times \frac{L}{16}$, rounded to nearest 10 BF (scale stick tally drops trailing 0).
