Did i got i right?
expiry, queue, scantime we need to delete from config file/not need them at all?
From what I can tell they don't actually matter that much as long as you just submit all your found shares regardless of what your client thinks of them. Mine thinks 100% are rejects (well bfgminer; cudaminer figures it out right on default settings) but my actual reject rate from the server is usually about 5-10%
