Erm so I  all we're trying to do now at the moment though is, is to, to operate from the point of view of saying look, if you actually take all these things into account, we shouldn't be worse than we were  ultimately, once these systems have bedded in, we're doing more checking on letters for example th than, than we w we won't have to once we've checked through the first two months of auto-offs, and we're getting used to the new reports and so on and that sort of stuff, so we expect there to be a blip, but you would expect a learning curve in anyway.
