Tilt equation default
\[ F_i[\text{angle}] = \left( \frac{\lambda_1 - \lambda_{1,\text{ref}}}{C_3} - \frac{\lambda_2 - \lambda_{2,\text{ref}}}{C_4} \right) \\ \cdot \text{pow}\left( \left( \frac{C_1}{C_3} - \frac{C_2}{C_4} \right), -1 \right) \]
Fi[angle] = (((l1 - l1ref) / C3) - ((l2 - l2ref) / C4)) * pow((C1 / C3) - (C2 / C4), -1)
