As long as you shoot at ISO100, you'll almost never see noise, even with a 4-stop push. Unlike other cameras, the Pentax even takes shadow recovery well at higher ISO levels like 1600, instead of just revealing noisy shadows you actually get more shadow detail too.
This makes setting exposure very simple - just make sure the histogram isn't in the red and you're good.
I tried capturing this one scene with a 3-shot bracket and also equalized one shot to recover everything, the difference was surprisingly small, just a bit of graininess in the shadows visible mostly at 100% on screen. I'm not entirely sure what kind of situation would actually *require* HDR on this camera, as opposed to simply doing it for the lower noise.
