Thanks for the advice, making me feel a little less crazy.
After posting this I spent a good few hours going down the compliance rabbit hole only to find out that all of the manufacturers weight measurements were way off and my cart/headshell/screw were spot on where I wanted the whole time. At first I thought I was running a bit heavy, around 6hz, but after throwing everything on my scale there was a whole 10g difference from the specs I was using to calculate.
