Not at all, you don't sound unfriendly ;) I increase moves_searched every time I
make a legal move and search it. Futile and illegal moves are not counted as
they are not searched. The 99% was without nullmoves. 96% is with nullmoves
(after 1.e4 e5 2.d4 d5). If I do a 9 ply search from initial position I get
94.2% with nullmoves and 97.7% without.
