Interesting. I weigh myself every morning and notice 1-2 pound fluctuations that I can't correlate with food. I have also occasionally noticed the drop in water weight immediately after a long/strenuous ride which doesn't seem to last until the next day. I always just assumed the return weight was just water replenishment to normal. But this glycogen repair deal may have something to do with the unexpected 2 pound jumps to what I would call a high normal that I occasionally see. Whatever, it is all academic since I am primarily concerned that my weight stays consistent within a +- couple of pounds range.
