Models #APCC

I have a pretty big model in APPM and I am semi-permanently mounted. I have the Mach2 on a Losmandy HD tripod on concrete blocks. My dirt/lawn is largely clay, so even though I am well polar aligned, it drifts often due to the soil shrinking when it gets dry. So my question is, while there have been no other changes to my set-up, the altitude of my PA does change, so is my model now useless? Thanks in advance.
