The problem is you must inspect every game to see if it is legitimate. Sometimes Ruffian will quit before the game is over and the GUIs will assign an incorrect score to the game. These must be weeded out of the results and replaced with new games to keep the balance between white/black. An alternative is to finish the games manually. I have done both depending on how close to an "end" the game is. Jim
