Can you just explain how that would work though 'cos we're now erm, auditing by job, aren't we, and given I don't know the audit timetable I can't visualise the effect this would have but it seems that one could be making a change 'cos a particular, a job's been audited and it effects Q P1, or something one month, and therefore you make changes to it and another job's audited the second, another month, the second month and Q P1 needs changing again, and it, in terms of keeping our staff with us, it will be quite conf , I think it's not terribly practical to keep having constant change.
