I think that has been clear for quite a while. It is also worth noting that the two extra people are eating and breathing (hopefully) and using other resources that were not budgeted for. It is not a problem short term. ISS is supposed to have supplies for 3 or 6 months (I cant remember which). But this will mean that the next supply shipment needs to be heavier than budgeted for.
