Hi JD. I thought I'd point you to another post I've saved a link to through the years... it goes to my questioning of calculation methods for compression in the panel for a given deflection of a given rib. Robin hasn't been a contributor for quite some time now. But he provided a lot of good food for thought. Check this out and please give me your thoughts.
