An example:
I read your summary and it appears accurate. I think there was one small typo. You wrote "For double, drop (0.615284) we get an equity of +0.82039823777416349539". I believe you meant "For No Double (0.615284) we get an equity of +0.82039823777416349539" The key thing to note is that mwc2eq (implies match play) requires information from the match equity table (as you have stated), so for match play you must get some data from an external source beyond the computed values in the SGF file. Of course if you are analysing a money position this isn't an issue (since match equity tables don't apply to money play). On a side note, one other value that can be computed from the given numbers is the equivalent money play equity (and is displayed at the top). This value can be computed with this equation: 2*W-1+WG+WBG-LG-LBG In his position that results in: 2*0.572881-1+0.222155+0.024300-0.139598-0.006174=0.246445 (Rounded to 0.246) -- Michael Petch CApp::Sysware Consulting Ltd.
