I can't imagine any compression or expansion of the swingarm side to side could be that significant on the length of each arm. Trig it out, and roughly it is a 2 to 1 (from my memory) would mean that compression of the arms (let's say .010) would only yield a length difference of only a few thousandths. Hardly significant.
Besides aligning the rear wheel has more importance that just tire wear. It also affects handling which is far more important.
In my mind, also, is the fact that this is a crucial issue so I still would trust Suzuki on the marks rather than just a lightly squealing belt.
Virtually impossible to measure oneself unless set up on a stand with a laser measuring device.
