Up to a point, but if you imagine a 100kg rider, on a 130kg bike, the rear spring has to cope with a massive increase once the rider is sat on it, so sag without the rider will be almost zero - hence the statment in post one that 'there is no movement... the rear just lifts off the stand'.

The bigger the bike, the less the ratio of rider to bike weight, so the rear sags even without anyone sat on it.

And yes, doing any kind of setup to an old, tired or simply wrong strength shock is a bit of a waste of time!
