Well, I don't think precision (related to horses) is very high here. But, the
HP was supposed to be what a quarter horse (NOT draft horse, Percheron,
Belgian, etc. even bigger than Clydesdales) could produce for a full 8-hour
or so shift, and be happy to come back and do it the next day. In other words,
kind of a standard work day for such a working horse.
