Eric,
Before I can reply to your question, I need to ask a few things:
1) Are you using solder mask over top of your vias?
2) If not, what size are the pad & hole of your vias?
3) Are you differentiating between pads & vias on the same net to pads & vias
on different nets?
Figure 3-24 in the IPC-SM-782 SMD and Land Pattern Standard (pages 26-29) may
give some of the answers you need.
