Another thing which you could do is to note how long it takes for your food and water to tick down by one in a given zone and then get a plains pebble and do the same thing. To be accurate, you'll probably want several timings of each instance to improve measurement accuracy. It will take a while though... I recall another rumor where it was believed that drinks were consumed at an accelerated rate in the deserts of Ro however I don't recall this rumor being verified..
