<VV> How to tell if shocks are shot

I don't really like the bounce test as it depends too much on the 
shocks.  Unless you know how they were new, then you have no real point of 
reference.  I just installed Clark's adjustable shocks on my sedan.  At 
stiff they barely bounce even.  At soft they bounce 4 times or so ... I 
have a Toyota truck built for rock crawling.  The shocks (double) are so 
hard that if two people work at it they can push it down, no bounce at 
all.  In my view the bounce test is only useful if you know how it behaves 
when the shocks are new ... my Sedan (set at soft) I know ... if more than 
4 bounces I am in trouble, otherwise the shocks are fine.
