yes, its really true. little changes can mean alot. i moved my saddle foward just a few mm and wow what a difference. now i know i have to have about 71 mm from the handlebars to the seat to make that good "cockpit" we're talking about. i moved the saddle on my 2 other bikes and had similar improvements. but hey, every action has a reaction. if u sit more upright u put pressure on ur sit bones and those longer rides start to really hurt the butt. so i think i've learned that the real solution is to have the most amount of handlebar positions as possible. that means eventually drops.
