How good is my opening, ChessBase?

In the last two decades I have probably played about 100.000 games online, most of them in blitz and bullet. And I have often wondered about my win/loss ratio in certain openings: Is my personal anti-sicilian system 2. c4 really working so well? How often do I win with 1e5? Did I really win more than 50% of my games with my favourite opening, the Naselwaus Gambit? ChessBase knows the answer to these questions!
