There are two possible difference between GradualTest and other such tools but
this should not give any different result if there isn't any error in the
engine.

1. The cause of the utility, you can have several moves as bestmoves with
different score for each move.

2. It use 'go' to start the search and '?' (move now) to terminate the search.
This is for any bug in the program when used in a game also should be reflected
in the test. It also would automatic go to the next position if the engine do a
move when it find a mate etc. and is designed to do this. Eg. you don't need to
wait for the timeout if the engine in real play neither would wait.

For only counting the last change of prefered move should be the same as in
other tools.

NB! Crafty in analyze mode (other tools) and in playing mode (GradualTest) could
give different results.
