i'll admit i don't follow the rankings very closely (i know it's cliche, but truly nobody does), but top 8-10 is a pretty natural breaking point between the "really good teams" and the "good teams". 15-25 usually seems to be where we fall, with the occasional surge. wins like this week are obviously great for the team, not a huge deal for rankings tho. that stuff's all 100% computerized (unless it's changed), and i think friendlies are the bottom of the barrel as far as movement goes.
pretty much if you kick complete ass in WC qualifying/confederation's cup, you're in a good spot
