25 | \(DIF_{OC} = 1.586\log \dot{\varepsilon } - 1.596\) | 0.91 | \(DIF_{CFRC} = 1.353\log \dot{\varepsilon } - 1.117\) | 0.99 |
50 | \(DIF_{OC} = 1.292\log \dot{\varepsilon } - 1.007\) | 0.91 | \(DIF_{CFRC} = 1.264\log \dot{\varepsilon } - 0.899\) | 0.96 |
75 | \(DIF_{OC} = 1.888\log \dot{\varepsilon } - 2.04\) | 0.92 | \(DIF_{CFRC} = 1.569\log \dot{\varepsilon } - 1.439\) | 0.92 |
100 | \(DIF_{OC} = 1.743\log \dot{\varepsilon } - 1.763\) | 0.97 | \(DIF_{CFRC} = 1.528\log \dot{\varepsilon } - 1.367\) | 0.98 |
