Dec Qtr Predicitons, page-79

I've found from my experience of tracking these shipments that most runs only have 4kt onboard depending on the total for each shipment - I know the Wunma has a carrying capacity of 5kt but if they do a 20kt shipment then they'll do 5 runs with the last run slightly longer as they've cleaned and scrapped the last bit of concentrate from the Wunma. But if they do a 10kt shipment then probably only two runs.
But I'm only estimating quantities for each shipment here so easy to be out slightly over the quarter.
