I think it'd be better to do it before you grill it cause while its on the grill it'll soak up all the seasonings and make it better tasting then it would if you would have salted it afterwards
Since the death rate is higher than the birth rate we can assume that it will be negative. 5-15 is -10 for their life. immigration is also lower than the emigration. 2-4 is -2. adding -2 and -10 will give us -12, hope this helps.
