Luckily, the GSXR shock can take care of both spring rate and damping settings (assuming you choose one with a spring matching your weight) so you don't have to choose one or the other.
Can show up like this;

Rear chatter while hard on the front brake (harder than your average track rider)
Front pushing because rear will not give up enough travel/speed of travel so the tires, forks and frame must absorb the force
Numb feeling of traction from the rear - too much preload or wrong spring
Too much track feedback from the rear - too much preload or wrong spring

It just seemed to me that a lot of people didn't know/care what they needed for their weight or what they were installing - they just heard that a GSXR shock was an upgrade so they bought the cheapest one off eBay. A different year 600 or a 750/1000 might have a spring that better matches the person's weight, rather than just duplicating the stock numbers. Maybe I'm just reading too much into it, but I got the impression that people weren't necessarily informed enough to make the best decision. If you can just make a slightly different model choice when buying your GSXR shock and get one with a spring better suited to your weight, it makes the DIY that much better.
I think you're pretty much spot on.
