New description:

 Initially, `v3bwfile.py` was just converting measurement `Result`s to a
 `Bandwidth file` lines format.
 Then we started to apply scaling methods and filtering the measurements to
 satisfy certain restrictions.
 To don not have to modify code in other file/classes, all of that was
 implemented in `v3bwfile.py` classes/methods, but it should be moved to
 either an intermediate file/classes that deal with the statistics
 calculations (and not the format) or modify `Results` to be able to
 perform those calculations.

 Edit: fix typo
