Re: [Bug-gnubg] Wrong luck adjusted result on Grandmaster

[Timothy Y. Chow]

Luck-adjusted results are computed using MWC while designations such as 
Expert/Beginner/Awful! are computed using EMG.  I suspect that the same is 
true of Go to bed/Go to Las Vegas.  My guess is that Richard made some 
relatively small EMG errors at a late stage in the match where they made a 
big MWC difference, while his opponent made relatively large EMG errors at 
an early stage where they made only a small MWC difference.  A similar 
issue may apply for the assessment of the overall luck.

As for Ian's DMP test, I believe that the luck-adjusted result should 
ideally be zero, but if the analysis was done on a different level from 
the playing level, that could cause a discrepancy.  Also the average of 
the equities after all possible rolls should theoretically equal the 
current equity, but if you use 2-ply (say) to analyze the equities after 
all possible rolls, and analyze the current equity using 2-ply, then the 
former might not average out to the latter, because 2-ply isn't perfect.
