It may be not good enough to calculate loads in mean section of a spiral bevel tooth. It does not give you a correct result because:
1. The tooth has different spiral angle on different sections so the contact point moves during the rotation and change directions of the loads
2. The mean contact location depends on gear setting so the loads
3. The old formulas do not take froction in to account

In general you may think that the old way is OK. But in some situations it may generate a critical error. For example the avarage load may be pushing pinion aut of the mesh so the designer will not do anything preventing the pinion get pulled in to the mesh. But in some positions the pinion can be pulled in to the mesh because of the real load is changing during rotation.
