Hi MikeThe approach looks quite interesting. It seems that you have been
able to create segments small / Medium and Large such that users will
get Medium when not falling into Small. So, small is a subset of Medium.
However, then you have created two mutually exclusive groups to split
Small into 2 buckets. Such still maintaining the hierarchy. So, yes, you
should be able to target these in the right order and get sense of
difference between them. Go ahead and try and do share the feedback.
