Hi Bcook,
Comfort levels are very subjective and individual and depend on many variables (see mattress firmness/comfort levels in post #2 here). Your own testing and experience will be a much more reliable way to assess whether a mattress is a good match for you or how it needs to be adjusted than any “theory at a distance”.
I’m not clear from the information you provided what you are looking to adjust or what you are experiencing on your mattress but there is more about some of the more common “symptoms” on a mattress in post #2 here and the other posts it links to that may be helpful.
