As mentioned in the reading, there is no magic setting. Meaning those settings between 1-20. It's either too much power where the drill keeps wanting to rotate eventually causing the screw to dig the drilled hole out or not enough power causing discontinuation of drilling the screw all the way in. I also understand that there is a drill setting as well, along with a hammer setting.
I'm more interested in the feature that provides a safety net that doesn't overturn screws. as mentioned above, dewalt has this feature and no tools review even mentions this factor through youtube or any vendors. When you drill in screws and a resistance is met the drill detects this and resets its mechanical rotation and doesn't turn the head of the drill, hence a continuous clicking noise.
