Right. So it'd be round down(territories/2)+round down(population +[1 if odd number of territories, 0 if even]/3).It'd basically provide for a faster bonus for taking territories than what is offered, but leaves the population at the normal level. You get less advantage in that you are still rounding down, but but can start getting bonus armies at 8 territories instead of 10 and even quicker if you have a major city to start in.
When you think about it, the other IB power doesn't give you 2 cards unless you expand 9 territories (minimum 1 troop for 2 coins worst case) and this gives you a bonus army once you get 8 territories (if 0 population. Then the choice between the two becomes, get a shot at a couple large multi-coin cards for 9 territories or find a population boost/expand faster to get at the quicker territory bonus.
