My Mega 99.cbh Database has 1114444 Games 54,277 Opening Keys 56,004 Opening positions My Big Database 2003.cbh has 2312073 Games 55,917 Opening Keys 56,947 Opening positions My eco,pgn has 2014 ECO Opening Classifications with moves.. I think we can "Classify" any Opening or game played or tested. I have presented which ECO Classification is better for White & Black. Now using this addition Data & Links I have presented, you can check them out yourself. I must disagree with your conclusion.
