It's not about "total hash/s", it's about "total unique hash/s". If everyone in the pool is assigned a subset of all hashes to work on (sizes based on each nodes average hash/s), then we'll guarantee that no hashes will be repeated.<br/></div><br/>This is already guaranteed because everyone has a unique public key in their block. You reminded me of another way that pools are bad, though: since everyone uses the same public key, they have to do weird things with extraNonce, which increases the size of the block header and makes generating more difficult for them.</div> text/html
