Hi Tinino, The splits that VPB uses are required to control how many levels get built by each indivual osgdem task, the more levels built by each osgdem task the more memory it uses and the more time it takes to run, but of course reduces the number of tasks required to complete the overall build. The key constraint that is optimized for is the memory footprint. As VPB only equalizes the colour and normals within the tiles of a single osgdem task having more tasks results in more tile boundaries that might not be perfect matched, this is usually something is very visible but can be something to be aware of.
