If I read correctly, neither.
The pool would prefer transactions to addresses which have not been reused.
Are you saying it would prefer addresses that have no record of use in the current block chain? If I'm understanding it correctly, it seems like this would be a tricky situation because of the payout method used on this pool. I was operating under the assumption that I would continue to mine until my reward reached something around 0.16xxxxxx, at which time it would enter the payout queue. If I wasn't at the computer to immediately switch to a new address I would continue to accrue a small amount of coins that would probably be lost after switching to a new address because they are under the minimum limit. Please correct me if I'm wrong.
Thanks!
