Someone could say that they have 600rwhp with no return system, but that doesnt mean it shouldnt have one... fuel pressure is going to drop towards redline when you are looking at that type of flow through stock plumbing especially when the pressure is regulated before rather than after incoming flow restrictions. Most tuners will find fuel pressure drop to be unacceptable because any system that is performing beyond its limits is going to lack consistency and without consistency in your fuel system you cannot really consider the setup to be truly dependable.

All aside from that, nobody ever really considers how efficiently their individual car is consuming and burning the fuel that its supplied. If two E85 370zs are running identical builds but one is tuned to 17 degrees timing and the other is tuned to 23 degrees timing, you are looking at 2 cars producing a variance of 75-100hp out of the same exact fuel volume. Timing is only one of countless values that can effect the engines ability to efficiently turn fuel into horsepower. Odds for or against you can reach the end of a fuel system a couple hundred HP apart. Some guys think a Walbro 255 can only support 400rwhp but I have seen them make 670rwhp! Its all over the place.
