How to analyze great number of games?

I have downloaded hundreds of my blitz and bullet games into chessbase and I am trying to analyze them. I try to analyze not just the opening theory, but overall flaws in my chess thinking and mistakes i tend to do quite often. 

For opening theory I use opening books and I switch to stockfish when we play out of the book. I try to analyze why it was out of the book move and if it leads to significant drop in evaluation I analyze what was bad about the move. For the rest of the game I am just going move under move checking stockfish evaluation and when I see some significant change in evaluation, I stop and think about what was bad about the move and what better options I did have. Sometimes I do the same for the opponents moves. 

What I try to avoid the most is to check the best moves suggested by stockfish before I do my own little analysis

I dont know if this is the best or the most efficient way to do as it is rather slow and I use an engine a lot, but I didnt figure out any better way

The Explorer here generates useful information.

For example, it seems to suggest that you have had bad luck playing against some lines in the Sicilian.

Have you tried it? I believe it will populate with more of your games after you use it.

Thanks, I didn't know about this feature. Though it is little bit disappointing that i cannot choose only games played this year for example.
