Large game databases show that all things being equal white should trump black about 54% of the time.
Do your results conform to that? Here's a forumla to calculate your %preference for white?
Score = 100* WS/(WS+BS)
where WS = (WW+WD/2)/WG and
BS = (BW+BD/2)/BG
BG, BW, BD are black games, wins and draws, and
WG, WW, WD are white games, wins and draws. You can get this info from the "Your performance" page on "My Home".
As an example, my score works out as:
Score = 100 * 0.8324/(0.8324+0.81768)
Score = 50.4%
Which compared to the 54% benchmark tells me that I play relatively better as black than white. It could mean my openings as white are weaker than they should be. It could mean my defences as black are stronger. I'd like to think its the latter.
What is your score? And what does it tell you about your game, if anything?

I'm not sure what I'm doing wrong...
Here's my formula...
100*(173/161)*(108+(13/2))/(117+(8/2))

I'll edit it.... Hold on.
Okay, fixed. Sorry!
Ragnorak - your score is 100 * 0.7111/(0.7111+ 0.6994) = 50.4%. Same as mine.

That is extreme. Did you apply the formula? Just calculating your win percentage as white won't do.
the numbers are
WS= (76+7,5)/157= 0,532
BS= (142+12,5)/185 = 0,835
Score= 0,532/(0,532+0,835)
Since I just won another with black the value adjusts to 38,8 %
btw: maybe the result is affected from absolute game number, since I tend to play black, when challenged
WS = (196 + 17 / 2) / (196 + 17 + 102) = 0.6492
BS = (195 + 20 / 2) / (195 + 20 + 106) = 0.6386
score = 50.4(1)
Except for very strong players I think when you are black you are compensated for white's initiative by being able to choose the defence. As black I can always play the Sicilian after 1.e4 but if I play 1. e4 as white black might do anything.
