Re: your last point.
No, you've changed the length of the lever arm, so the actual ratio is different. eg if you increase your chainstay length, increasing the spring rate doesn't change the leverage ratio back, your shock is just experiencing more squish now, and you need the extra spring rate to get you back to appropriate sag, etc.
