A quick google will take you to a number of studies. It takes a little digging to find the actual studies, rather than the various product websites, but the studies are there. You'll quickly get into the weeds of what specific forms of carbs (i.e., fructose vs maltodextrine, vs glucose, and at what rations) are usable at what rate. I got as far as finding a ratio that works for me and is affordable, and I can dial in the number of carbs per hour relative to the workouts/races I'm doing.
