I run some more detailed tests on geonames and two smaller datasets from

Thanks. I'm going to continue work on application of this split method in following areas:
1) range types
2) seg contrib module
3) cube contrib module (there situation is not so easy, probably some heuristic of split method selection would be required)
Do you think that separation of some common parts of algorithm implemetation is resonable in order to avoid code duplication? For example, different application of algorithm could share function of splits enumeration along axis which takes pointer to consider_split as an argument.
