Its all about where you hit the joint.
Just mess around with your replay, you can always use the "E" key to edit your replay. But for madmans, they really just take time and effort, so the longer you work with it, the more likely of a chance you have to come out with a pretty nice replay.
Im not much of an SP person, i stick to MP, but even in multiplayer hitting joints in key spots helps, even levrage can take effect.
