I have come up with the prediction for the 72nd draw.
If it happens on:
Sep 13 -
CRS 429 - ITAs 2787
Sep 14 -
CRS 430 - ITAs 2660
Sep 15 -
CRS 430 - ITAs 2842
The variance in the above calculation is +/- 1 CRS.
Please find below the CRS cut off on each date (in case the number of ITAs issued is more/less than 2800):
