One comment regarding z-translation. You say that each figure moves a certain number of distance units per cycle, but you do not (as far as I could see) say what distance units you are using.

From the numbers (human figures 6.059 per cycle) I would guess you are using feet, but you should really state this, so that less experienced Poser users know that they have to convert the numbers to whatever units they are using.

Oh I didn't know it was feet. I was just going by the zTranslation value in Poser... but you're right, if you're using Daz studio would it be a different value?

Thanks for letting me know and your help

Cheers
