Erm we did an initial pilot run of nine hundred and seven, er and we had them redirected here which was quite fortunate cos we did find some er previously unthought of errors, erm  there were two categories, these are ones where, since the renewal date, they've had er a decrease erm sorry an increase which meant that erm we're now quoting on their benefit statement as at last renewal, they've got today's er premium which of course is wrong, so we've had those redirected  in future, inside here.
