Jeremy, before delving into this further, can you check if your Cacti calculations are compliant with the following tidbit from http://doc.powerdns.com/recursor-stats.html : "It should be noted that answers0-1 + answers1-10 + answers10-100 + answers100-1000 + packetcache-hits + over-capacity-drops = questions." In addition, you might want to look at the rrd metrics. In short, if packetcache-hits are not counted as cache hits, the total cache hitrate will be wrong.
