Rankings in the Telerik forum are generated dynamically and
depend on all forum posts (by all clients). There is no fixed minimum count for
these three ranking groups.
Let me give you an example. For Intermediate Ranking today
the minimum count of posts may be equal or more than 50, but tomorrow it might
be equal or more than 55; that value depends on the forum activity. The same
way are calculated and Masters.
Hope that explains your question.
All the best,
the Telerik team
