I'll let you know, I'll be going in for a pinch soon -- my Tanita is reading 24% but the mirror tells me I have the same padding as I did when my bf hit about 20% last year.
Koffee's point was that the only way to know if your weight gain is muscle/lean mass or fat is to compare apples to apples.
Assuming that the Tanita is consistent if not accurate, 12% bf at 162 vs. 15% at 170 indicates a gain of about a pound of LBM, so yeah, you could be gaining muscle.
(In general, a body puts on fat and muscle at the same time (in a condition of excess calories), and takes off fat and muscle at the same time (in a condition of deficient calories). This is why body builders do bulk and cut cycles instead of trying to gain muscle and lose fat simultaneously, which is impossible after a short period of "newbie gains".)
