Othello Alpha Beta Pruning

Has anyone written Alpha Beta for Othello before? I just wanted to make sure I was doing this correctly:

The maximum gain one side can make with depth 'd' left is:
(Assuming each piece is worth 1, corners too for now)

d max
0 0
1 19
2 19
3 38
4 38
5 54
...

Am I missing something? My miniMax and Alpha Beta play differently. Is my mistake in the stuff above?
