I haven't backed off anything. My thrust is to ensure the availability of 
carbohydrate \-based substrate.

A supposition unsupported by any research that I know of. Having a reservoir 
of water in the gut is other than having body fluids in circulation. I'll be 
interested in the science that says gut reservoirs of water translate to 
retained normal fluid balances during extended exercise.
