A couple of suggestions....
I originally put my set on this calibration...it was better than the factory setting. But sets and ambient lighting situations differ. Actually calibrating your own is definitely the way to go. I had the good fortune of having our own Majorloser recently calibrate our Panny in situ. The improvement was astounding.
Also, please remember to write down or photograph your settings, so that when you want to make changes or get a power-down default reset, you know what to change the settings back to.
Isn't it fun when you get that nice 3-D type image coming at you?!
