Telengana(s) are good from an administrative point of view

Smaller states are better, but should we wait to find differences to create them? i have been saying for a while that there should be a formula to calculate the most efficient size of the state. State borders should ideally be straight lines – there is no need to create or encourage  regional feelings by putting people with similar language, culture into one state and allow them to differentiate themselves against people from other states.

Let us have smaller states by all means, but we should not have smaller states based on regional and sub-regional feelings, but for purely administrative reasons. And in case we have states for purely administrative reasons, shouldn’t the borders (or which city falls in which state) matter at all? Or, would it matter if we had straight line borders like some states and even countries have?
