The answer to this age old question has perplexed people for eons.
Part of the reason the question is so difficult to answer is that the amount of wood that woodchucks would chuck on a given day varies greatly with the seasons and with the metabolisms of any individual woodchuck.
Modern internet technology has advanced to the point that we can reliably monitor the amount a woodchuck chucks in real time.
The results of this monitoring are shown below. Please note that the numbers vary due to the dispositions of the woodchucks involved.
Average amount of wood a woodchuck would chuck in a given day 457 butt cords of wood.
Median amount of wood a woodchuck could chuck in a given hour 400 butt cords of wood.
Record high for woodchuck wood chucking of 8063 butt cords was attained on June, 15 1996
