Artie Wrote:The World at War ladder do not use exact Arpad Elo's formula, but with some modification. One major difference against the Blitz ladder (which is good in his way) is simple (and I wrote it to the Zemke too :)
The WaW ladder is skill based
The advantage of the blitz ladder is that you can sort the ladder however the user wants to. Based on skill, win %, games played, win streak, or ladder points.
The SZO ladder is similar, but another advantage that the blitz has over that (or any other ladder I have seen) is the great number of players and games that get reported.
