i am going to disagree with ram1000 on this. i don't think they are just "guidelines".
the shock manual is pretty clear on this point. I don't have it in front of me right now but it doesnt sound like they are inferring its a range for optimal effects, MX or otherwise. To me it sounds like they are laying down the min/maximums.
It states fairly clearly that the operator is to change the spring if the sag doesnt fall within the stated parameters. I think that if you don't stay inside the guidelines you are likely unduly taxing the shock and decreasing its lifespan. At some point I bet the adjustment and operation would reach the possibility of catastrophic failure.
If in doubt contact a suspension tuning shop; don't trust a bunch of blow hards on the net.
replacements are EXPENSIVE!
