I don\' agree with this hypothetical group theory
You say NSC has grouped the cases in multiple groups as May-Jul\'00, Aug-Oct\'00, Nov\'00-Jan\'01 Feb-Apr\'01.
For a single entity called NSC, is it not a single timeframe of May-00 thru Apr-01. Why introduce this hypothetical group concept. For that matter, why this lower bar of May-00? We can just say, NSC is processing cases eariler than Apr-01. (Of course, the assumption here is that this Apr-01 approval news is true!)
Any thoughts!
