Regarding the red dot being in different places: admittedly all the lenses I possess have aperture linkages so I don't know how you'd get on with M42s, but I just hold the lens with the back towards me, rotate till the protrusion protecting the aperture pin is at 6 o'clock position, then slot the lens into the body.

That's a variation on method 2, I suppose. However, you are confirming that no Pentax user needs to use their lens hand to press the lens release button.

I understand the dot issue, too, but it's not so hard to make that a fluid movement. I've added that information to the original post.

Eventually, I should take a picture to describe what I mean and add it to the above article. But the gist of this article is that you need to develop some memorized motions to do it quickly, and the lens dot is no exception.

I just hold the body with my left hand underneath and press the button with my middle finger (of the left hand). Right hand just removes the lens.

The real problem with Pentax is that all the different (and old) available lenses have the red dot in very different places (on the end of the lens, on the rim, etc). I'm trying to learn which way around the lens goes by the aperture lever, but not all lenses have that either (I believe the M42 adapter doesn't?). That's what takes time, not removing the thing.
