Jon, If your product is not class three and you are getting at least 180 degrees on the solder side 75% vertical fillet 270 degrees on the secondary side (270 degrees around the lead) and 75% of solder on the pad on the secondary side you should be fine. If you require class three then it would be 270 degrees on the solder side, 75% vertical fillet, 330 degrees on the secondary side (330 degrees around the lead) and 75% of solder on the pad on the secondary side. That's from A-610 Rev C. If you are still not getting the flow you want try adjusting the speed of the wave. Lead free solder doesn't flow well so slowing down the wave and allowing the solder time to wick, will increase the volume of solder on the primary side of the PCB.
