Technically, if you are maintaining the solder joint minimums for all of the criteria it should be acceptable but most people will not want to accept that as a good joint. Most customers I have dealt with across all industries understand that there are minimums but do not want to take a minimum solder joint especially if there is a large void in the solder joint. Considering this then what are you left with? 

Are you dealing with oversized holes and small lead diameters?  Do you notice a difference if you slow down the wave speed a bit to allow for more of the solder joint to form?  Are you seeing the void area on leads or retaining pins?  Can you share a bit more info?
