Not sure is what you are looking for.
I went to statistics to get info about obj files:

obj 1
4800 facets - 4692 vertices - model
4800 facets - 4692 vertices - group Figure_1
3456 facets = 3490 vertices - material Outside
1344 facets = 1410 vertices - material Inside

obj 2 (2 of them)
19264 facets - 9804 vertices

obj 3
21649 facets - 18257 vertices

obj 4
4262 facets - 4205 vertices

and primitive prop ball

Coincidence or no but objects 2 and 3 are exported from Bryce 5. Obj 2(bubles) were *obp; obj 3 was *3ds. I suspect they are too big huh?
