What is the best way to get a ballpark compressiblity with XviD
dev-api-4?

I generally use XviD options like this on a two-pass encode:

v4mv:turbo=1:trellis:chroma_me:vhq=4:autoaspect

Should I use the bitrate produced in the first pass calculate the bpp
and use a percentage of that.

However, I know that XviD turns off some of its quality enhancing
features to speed up the first pass so is it perhaps more accurate todo
a partial fixed_quant=2 with these options calculate the bpp and use
some percentage of that?  

Is 60% of this bpp a good value?
