GP asked for the games from the sample provided which had the highest % of matchups; that's what I gave him. As already stated, I did not reach my conclusion that she was an engine user based solely on those games but upon the cumulative evidence.
I will say that a 100% matchup in a game containing 55 non-database moves is pretty much unique among the games I have analyzed (and that's in the thousands).
Originally posted by RJHindsI'll ask the stupid questions, you've damaged your credibility enough already.
When you do your percent checking for engine use. What moves do you
check? That is, it would be misleading to check all moves, since some
moves are considered forced and nobody in his right mind would pick
a different move. I suppose you would not include established opening
moves either. So how can you tell which moves are outside of the
mormal mov ...[text shortened]... e should see and those that may require
computer analysis and should be included for the study?

I found 4 more database moves by each than SB/Z's analysis side in this game: Game 5742978

I thought there was a Weyerfritz vs Seadevil game which was 100% top 3 match for both sides over sixty odd moves?

Firstly, the sample size of analysed moves is usually 700+ (often more like 800 or 900) so a few ply here & there makes little difference to the over all %'s if the match rate is very high.
Second, just because a move is still just about in book, doesn't necessarily make it a top engine choice move, so analysing such moves can be useful.
