yup it applies to poser4 too...in my last thread about this a day or so ago i came to the same conclusion,but didn't post it.while looking for a system scale for 3dsmax that matched poser's...i used dr.geeps measurement prop,and imported it into max,at 100%,the system scale that makes it exactly the nine feet it's supposed to be is, 1unit = 8.333 feet...the extra third of a foot is from who knows where,possibly an error in the size of the prop or possibly inacuracies in poser itself...
