I thought the same thing when I started a couple months ago. Some of us are just blessed with faces of steel. Ill second that you are coming along nicely and to not rush it. One of the best parts of the straight road is turning a quickie chore into calm soothing time massaging your face with a nice brush filled with good smelling warm lather.

For the skips and bumps, slow it down and keep a very shallow angle to your face. I find the buffing technique to help those spots.

I feel you about the hair under the chin, good news is that no-one can actually see those hairs even if you can feel them. I would either have to dislocate my should or poke the razor through my throat to get those whisker ATG. But a WTG pass makes them invisible to everyone else's eyes unless your job requires a lot of public staring straight up into the sky. I have tried scything and buffing to no avail, but I am still new. I know how I can get to them, when I am all dry and at work I can stretch the section onto the flat of my jaw, pulling hard and burrying my chin in my chest. Dont work well when the skin is wet though.

Take my advice with a grain of salt though, I can buff my chin until I can see blood spots under the surface. And that dont bother my face, its fine before I can get dressed and leave in the morning.
