Yes, Nic sorry; it is not a valid point on my part.As to runtime, not a valid point. The aim is to extract maximum effect asap before that darn thief entropy turns up
The mass to axle point is valid if you mean this : http://www.youtube.com/watch?v=Ud22NkZJG2Q
Balance point of the wrench is one cm off ratchet towards handle, so it's fulcrum heavy, making a bit wheel like for the most part of it's weight, but that doesn't expalin away 400 + grams.
Yes, that is what I am talking about how much of the missing 400g goes back into rotation after it starts to swing?640 gram of tool and it only registers as 200 gram to maintain at horizontal.

In this video can you take your machine apart and weigh the pendulum arm, wooden hub and bob altogether on a horizontal surface. We would be interested in how much more it weighs than your static mass.
I was interested at one time about leveraging falling mass as it falls than giving it back before impact. May though the reverse can be done.
