It would be great to see win loss stats from openings, even black or white dats
You mean, like these from the Game Explorer:
Only your "online" correspondence games are included but it looks like you play the Nimzovich Defense as black against e4 and the best thing we can say is that you have a very unfavorable record playing it, losing 75.6% of the 45 games you have played with it. You have won 8 times, lost 34 and drawn 3 times.
Statistics like that might lead some people to question their choice of opening. My guess is that your track record with it is understandable since people can use databases to help them play unfamiliar lines in "online chess".
The Nimzovich might be effective for you in live play (I can't say since the statistics aren't available yet for your live games in the Game Explorer) but people seemed to have the Nimzovich figured out in "online chess" against you.
