I didn't say it wasn't possible, I'm just saying the goals you set would be very difficult to acheive. When I was at 200lbs it took me nearly 3 years to increase to a 300lb bench (doing things naturally, which I'm assuming you will be too). It's "possible" with the proper diet and rest, everyone is different. I would personally worry about your 10-12 week goal first then work from there. You will eventually hit plateaus and theres many ways to break out of them....switch exercises, change the weight %, tweak your diet, rest more, etc.
