I think that you will find the answers to your questions in the book : Optimal Hand Evaluation (recently published by Master Point Press and available for ordering through Baron Barclay or the Bridge World on-line bookstore). In that book, the author clearly identifies all the flaws of existing point count methods and demonstrates the vast superiority of the Optimal point count. It should become "The Standard" in Hand Evaluation point count. Oh, by the way, it also shows that the Banzai point count has no statistical validity whatsoever and is actually quite absurd. Good reading !
