Granted, it's not perfect as we all have different body types, weight distribution, gender..., but still, it's kind of interesting to look at, espcially when it gets filled.
If you go to this cockeyed website, scroll down, and on the right hand side, under new features you'll see where you can click the height/weight sample.
Just something kind of fun to look at and get some idea.
Who knows, maybe we'll see some MF success stories on that graph

Enjoy!
