Hi Yosemite:
Adam's setting applies Strong NR and to me, it kills a bit too much detail. Medium NR does a much better job in this. In my first post in this topic, I provided a comparision and you can esily see the difference.
Regarding to the Exposure value, understood that my approach seems to have the same Jpeg Exposure value with the about 0.7-1Ev lower ISO stop. However, what I would like to know is whether the Exposure that K-7 Jpeg provide to us is the same as the RAW Exposure value. If it is the same then yes, my aproach doesn't have much advantages.
I've brought this matter up in this post.

Cause no one would like to check, I did the simple test myself. The result show me that the RAW exposure value seems to be 0.7-1Ev lower than the Jpeg Exposure value. This is my test result.

So if my finding is correct, K-7 Jpeg engine pulls Jpeg Exposure up for about 0.7-1Ev from its RAW Exposure (to me this RAW exposure might be closer to Exposure value that the sensor is actually received). And I just bring its Jpeg exposure back to actual (so call sensor) exposure.
My finding might not be accurate, therefore, if anyone of you is interested in finding the real performance of K-7 (which mentioned by most of the Reviews: K-7 RAW noise performance is equivalent to its competitors in its class.) you could do your testing and share with us the result (it is better to have some pictures) whether it is good or bad!
Thank you all for your discussion.
