I have to admit that although I get on the throttle a bit once in awhile...most of the time, I have a tendency to ride like the old man I am. I keep the rpms down in the lower end of the rpm range. Even if I'm not feeling like an "old man", I am boxed in often by cages that don't move all that fast. So I often find myself riding in the lower rpm range again, instead of keeping the engine to the redline.
So I looked at the chart and decided to disregard the redline area and looked at what the benefit would be at the lower rpm range where I'd probably spend most of my time at. I'm guessing at about 5500 rpms, there's maybe 5 hp difference between the baffled and non-baffled horsepower figures. And less at about 3000 rpms.
I doubt I could feel a difference.
Now is the time you start throwing rocks at me...
