The amount of work
that is accomplished is dependent on the design of our device- to say that
at the end a certain weight was only lifted x amount in each case does not
prove that the unregulated case is not capable of doing more work. My

Exactly. And in this case the regulator is the only feature
of the system that can be blamed for the reduced work
output.
