Re: [Bug-gnubg] Re: The importance of METs

[kvandoel]

Now that  the external player  bugs are dead  I tried playing  some 17pt
matches expert-expert using different met's.

I  think the  results show  that the  differences between  the  mets are
completely negligible in terms of equivalent rating strength points.

Playing 100 17pt matches  mec26-woolsey, analyse using woolsey.xml (also
at expert  level) I get the  follolwing effective ratings  for the mec26
table with 2200 being defined as expert level. On average the difference
is a single rating point caused  by cube "errors".  Of course the expert
level analysis  only shows how  small the difference between  the tables
is.

Let me know if anyone is interested in comparing other met's.
