I'm nearly sure that the concept is an "average" of what was
experienced in those days. Probably used to compare things for
equavalency in order to negotiate trading.

It is true that any horse can lift any weight given enough rope
and sheeves. Of course, there comes a time when the horse is
primarily overcoming the friction of the multiplication device
and not lifting anything fast enough to measure in a reasonable
length of time :-).
