This is not so when the net effect of all the other design revisions are factored in (please see my most recent post for an explanation). Perhaps the writer to which you refer used a word processor to achieve his test results, as opposed to the other alternative - building an action model. The result for our action is that the friction for every part/lever of the action is reduced. How could we get a friction weight of 5 grams if increasing the roller distance increased friction?
