I have come up with the prediction for the 68th draw.
If it happens on:
Jul 26 -
CRS 434 - ITAs 3200
Jul 27 -
CRS 435 - ITAs 3200
Jul 28 -
CRS 435 - ITAs 3200
The variance in the above calculation is +/- 2 CRS.
Please find below the CRS cut off on each date (in case the number of ITAs issued is more/less than 3200):
