I just set up a little spreadsheet ( for AG) comparing this methodology to the one used by Arnie Baker in Bicycling Medicine. Of course, it is anecdotal based on a statistic of one (me) but it seems more accurate and useful. It gives a min and max calories per hour needed during a ride based on how quickly your stomach can absorb nutrients.

Just thought I'd share my little experiment. Sorry it isn't as interesting as Nanci's coffee beans in the teeth research project.
