I'm running BFGMiner 3.2.0 against the Eligius pool. I have just reached enough hashing power where I think I could benefit from raising the difficulty of work units handed out by the pool. I have gone and told Eligius to hand out a minimum difficulty of 2.0 work units. I have run for a while and the work units continue to be difficulty of 1.0. So I decided to try the '--request-diff 2.0' argument. However, the pool is still handing out difficulty 1.0 work units.

Since BFGMiner is the recommended for Eligius I'm surprised that neither methods are working.

Is this a bug in BFGMiner?
