| Table 5. Prescribed fire rate-of-spread (ROS) prediction error for individual and mean predictions. | |||
| Fuel model | Rate-of-spread prediction error (ft/mi.) | ||
| Mean error | Min. error | Max. error | |
| 1 (Short grass) | |||
| Individual ROS | 9.7 | -15.4* | 39.6 |
| Site ROS | 8.6 | -1.1* | 16.9 |
| 2 (Timber and grass) | |||
| Individual ROS | -2.5* | -26.4* | 7.7 |
| Site ROS | -2.2* | -7.5* | 0.55 |
| 3 (Tall grass) | |||
| Individual ROS | 20.4 | -16.5* | 88.0 |
| Site ROS | 17.6 | 3.7 | 33.2 |
| 9 (Hardwood litter) | |||
| Individual ROS | -9.7* | -36.3* | 0 |
| Site ROS | -8.7* | -22.2* | -0.55* |
| * Negative values indicate rate-of-spread under-prediction, e.g., fire spread faster than predicted. | |||
