Plus, if what you said is true, then why not just do 5-6 sets of bench presses and leave. Why bother doing inclines, declines, ect. If you're doing incline press, does your lower pecs push up the weight? Or does your upper pectoralis portion do most of the heavy lifting? ;) Here's a diagram that could clear some of this:

Actually as of now, I'm doing DC training as you all know. I stopped doing flat bench altogether and my chest is growing considerably larger than when I used to do heavy bench press first (Max-OT).
Or we could both submit a picture of our chest to see who knows what's best
