Subject: Is this how Alpha-Beta results should look ?

I converted my BruteForce code to include Alpha-Beta code.

The pieces are setup for starting a new game.
I do not have an evalutation function yet so I just return 0 (zero)
at the Leaves of the tree.

Do the results shown below look like the Alpha-beta code is working correctly?
It looks like every jump to an even node increases by 2 fold while a jump
to an odd node jumps by the average number of moves at that ply.
