Should detail brushes create orphaned polys?

I'm not sure if this is really a bug or not. It seems that each detail brush i add to my map creates orphaned polys in the scene. Is this normal map2dif behavior? Could it be a bug in the calculation of the number of orphaned polys?

When i delete my detail brushes these "orphaned polygons" go away. From the reading i've done on the forum some people say they matter, some say they're random, some say they ignore them.

Oh yeah, you can usually just ignore them. I think they are polys that are inside other brushes and you can't see them. Since they are detail brushes, those orphaned polys get rendered anyway (unlesss they backface). It's probably OK if there are just a few in there, but when it gets to be many thousands it could affect performance.

Now that makes more sense than other explanations i've heard. Thanks Brian.
