Quote - yes it conforms fine in Daz, i use 3.1,

although it seems choppy when i move the arms up and down.

The "choppiness" is probably your falloff zones.  They likely need to be improved.  It may just be that the falloff zones are causing that in Poser, though I've never seen that happen even with bad falloff.

Have you looked at the falloff zones?  Your groups look good.

The "bulge" in the 2nd graphic with the arm up, is definitely the falloff zone.
