I think they can make an allotment on 6th itself, as all the groundwork with respect to application processing & in appropriate applications rejections and all must be already done by them quiet few days before, immediately after the closure of issue.
Now what they need to do is that they need to remove all the applications requested for withdrawal from the list and accordingly make the calculations and make the allotment. Also the application withdrawal request were to be sent to the registrar directly, so they can save some time there as well.
So, in short, allotment is possible on 6th if not then definetly by 7th.
