Seen from a slightly different perspective:
The DA 70 ensures the maximal possible resolution of the K-5 in the center of the image at 4 and 5.6 (about 2700 LW/PH). On the K10D, however, the maximal resolution of the sensor (ca. 2350 LW/PH, compare e.g. 31@4, 43@4) is not fully exploited (4: "only" 2200 LW/PH).
The obvious question: Why?
Maybe the AA-Filter of the K-5 is not so bad after all <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='

The AA Filter on the K5 is certainly weaker than on the K10D - it just has a stronger one than the D7000 etc. pp. And the AA filter has a different characteristic - the K10D has an asymmetrical AA filter whereas it's symmetrical on the K5.
We are also talking about 2 different lens samples here. In fact I was quite surprised about the similarities of the results especially because the K5 tests are more accurate due to more measuring spots.
So you are trying to spot contractions that do not exist from a real world perspective.
