In the most recents Crazy Analysis, Delta is the difference between the 
evaluation of this move, and the evaluation of the next position of the game.

For instance, in this page:
http://www.grappa.univ-lille3.fr/~coulom/CrazyStone/ingo/index.html

At move 72, delta = 0.0431076 is 0.441597 (value of K12) - 0.39849 (value of 
next position)

It is more accurate, because the next position is always searched with more 
playouts than the alternative move when analyzing the previous position.
