I seriously doubt that you're drinking 102 ounces of fluid an hour, particularly if you're riding for multiple hours. As the research cited above indicates, much above a liter an hour can't be cleared during intense exercise. In my experience, and based on the literature, if you're drinking that much all your doing is bloating yourself.
And 102 ounces an hour, over a few hours, even if part of it is Gatorade, has the potential to put you in Hyponatremia range.
One of the worst days i've had on the bike was a 110 mile ride, in 100 degree heat, done at a pace that was really too fast for my condition at the time. I drank a ton. Toward the end of the ride I felt terrible, and thought I was dehydrated, forced myself to drink more, and only later figured out, that I'd drank more than my body could abosrb, and that was part of the reason I felt like crap.
