Yes, I think, this is the case. For tree mode Scid does just
the same as you do if you set up a position on the board in
the main window and say "search board position". That way it
is consistent. Then it takes all games that contain the
current board _position_ (without the history, as you name
it) gets the next move and sorts these into the statistics
table.
Additionally, to Joosts comment that a perfectly valid move
is not listed: the tree is based on the base that is used,
therefore only moves that were actually _played in that
specific base_ are listed in the tree.
Maybe here is a point? In this regard it is e.g. different
from an opening tree or the like.
Its not that I want to defend this as the only way possible.
Just the observation how it works, that it is consistent
with the "search board position" function, and to explain
from which behavour Joosts observation occurs. So to say: to
define it, for us to speak about the same things.
I'd guess that changing the behaviour in the "board position
search" would also adjust the behaviour of the tree. I've no
idea how simple this is, however. And, probably, there is
even a good reason for it to work like it does. Don't know.
