You could either subdivide more, or alternatively run the Smooth Groups brush along the polygroup border to get a crisp line. The Smooth Groups brush is in the Lightbox Brushes Folder.

your polygroups are based on the lowest subD level, not the level where you created them.

Step down and you’ll see this happen.

I would personally break the object into pieces using the slicing brushes.
