Shoulder Press/Chest Press Ratio?

Sorry if the title of the post basically sucks but what I am trying to ask is if there is a general ratio of strength between shoulder press strength vs. DB chest press strength…

Can anybody post a link to a site for this? I would think this is along the same lines of strength ratios for hamstring / quads, etc.

I am interested in those ratios too. I have not been able to find any info though.

drawing a blank, but Poliquin had an article here, optimal stregth ratios or something.
