Hello Graet,
thank you for your correction. DGM was the name for slush's payment method that I found in a note to the pool. I always wondered whether this was really true as it didn't match with other statements in the forum.
In the forum notes I found, nobody ever gave a name to the method applied but I think one may call it Raulo's method, exponentially weigthed payout, "slush exponentially scored mining" or the cooperative sharing method. If there is a name to it, I would be glad to know it. Slush exponentially scored, as in your reference, is not too helpful in my opinion.
