I'm only 172 in my avatar pic (precontest pic), and I'm 5'9". Weight doesn't mean shit. I'm WAY bigger and stronger now than I was when I was 205. At that weight I was a flabby mess.
Point being, telling someone to achieve a specific weight that constitutes a "base" is sending the wrong message. The average American does it all the time without touching a weight. Saying they should achieve a certain body composition is the right message.
