I'm pretty sure W/kg is based on your real weight, not your "lean" weight. All the cyclists I've known who've lost significant weight have not lost power. So they're producing 200W, and after dropping 20lbs, they're still making 200W, but the W/kg has gone up. By his own math, the op is currently at ~2 W/kg. There's plenty of room to grow.
Depends, to compare performance, especially in climbing, W/kg is about real weight. However when talking about how much room to improve you have it should be about your "lean" weight. Reaching 4 W/kg or higher is only possible if you are lean. With 30% of fat, that is just not going to happen and you will hit a ceiling at a much lower P to m ratio than 4.
