What rules of thumb do we have for getting objects "in scale" in Poser? To put it another way, how tall do we think Posette, Vicki, Mike, the object cylinder, et al., would be in real-world feet and inches?

I feel sure DAZ has mentioned this somewhere, but when I ask them in a tech question, I get no reply.

So--anyone, please--what heights do you assign the figures, or what other rules do you have for scaling, and do you know of any "authoritative" answers to these questions from DAZ, Curious Labs, or whoever? Thanks.
