A Database for ICCF Finals

Last week on my World Championship Blog, I brought my page about correspondence championships up to date; see ICCF 20th to 24th WCCC Finals (PGN) for details. What to do next with these potentially instructive games? I combined the games for all 24 finals into a single database and loaded it into SCID. The software gave me the following breakdown of initial moves (1st move, 1.e4 responses, 1.d4 responses):-

When I first added the crosstables for the 1st through 14th championships, I analyzed the game scores and posted the results in Chess History on the Web (2001 no.24) : Correspondence Chess. I could do a similar analysis again, but I'd rather look at middlegames and endgames. How to do that? I'll post here as soon as I figure it out.
