I admit I didn't read all 17 pages.
My take on this: I was in the same boat, K3 II, 300/4 and 1.4TC. For perchad birds from hide I had no problems. Then I went to Farne islands in UK to photograph puffins. Out of over 1000 photos shot in 1 hour I binned 850 without even going to 100% view in lightroom due to missed focus. I was fighting with the camera all time I was on this island.
I had a choice: get 150-450 for 1200£ hoping lens will be faster and better at focusing, or switch to Nikon D7200 (D500 was out of my budget) and one of the 150-600 zooms breaking even and knowing it will be better.
I went for the latter and my next outing for BIF yielded 1500 photos with only about 200 discarded as obvious missed focus.
I also tried my kid running towards me and Nikon with 55-200 lens nailed every photo while I had problems with K3 II and tamron 70-200 (allegedly one of the fastest focusing screw drive lenses) in the same situation.
I still prefer Pentax menu and handling but for AF tracking performance for me Nikon is much better.

OK, so I just checked how it works on K3II.
First DA 300/4:
Lens with AF switch set to AF, camera to MF, pressed back button and it fires when no focus achieved.
Lens set to MF, camera to AF, pressed back button and camera doesn't fire until it's in focus.
M 50/1.7
Camera set to AF, back button pressed, camera doesn't fire until it's in focus.
DA 50/1.8
Camera set to MF, back button pressed, camera fires with no focus.
Bottom line:
CIF works with back button but you need lens with AF/MF switch.
Confused myself as I was sure lenses without switch worked. I never use it though so not much experience there.

I'd say you could have it worse: stuck in green mode would be dreadful.

Seems to be fixed with new firmware. Mine now works like it should.

I bought Canon EE-S from Amazon and cut it myself. Can't get much cheaper than this.
You just have to calibrate it after putting in camera by using shims. In my case I had to remove stock shim from K-3II and use it without any. Manual focus was easy, especially with longer lenses. I also have Canon split screen cut to size. This one require shimming and I've done it with narrow strips of low tack masking tape. But for manual focusing I prefer the EE-S screen.
Just one warning. A lot of dust can get into mirror box while you messing around with screens. I had dust stick to prism and screen itself. And cleaning the screen can easily get it scratched.
Good luck.

Apart from guide lines on focus screen do I see microprism circle in there?

Why do you find it so hard to belive?
Mine really focuses OK, I don't have the dock and I didn't replace it 5 times. It just works. Maybe I was lucky?
One of the first quick and dirty tests: handheld, available light, f1.8, focused just above A using PDAF.

It's just like Pentax SDM lenses. Would you say they're all lemons and will fail after 3 months? After all there are people who had them fail after few months so all SDM lenses must be duds following that logic. Do you find it hard to belive anyone got working SDM lens with all the reports about failures all over internet? And if not can you eplain why?

Simplest way to solve your indoor flash problem: LumiQuest 80-20 - LumiQuest
Flash head up, P-TTL (not sure about it working well on K30/K50 but on K3 works great).
I made one out of white cardboard, works a treat. Difference between straight on, bounced from ceiling and using this is amazing.

We need another one: It will natively accept screwmount lenses and K with adapter :P.

I had istDL2, K7, K5II and now K3II. Out of those K3II needs little to none exposure adjustment in Lightroom. The other three pretty often +0.7. But I belive they tend to underexpose to avoid clipping highlights (like Steve said).

1800x1200 pixels? That's just a tad over 2 MP. Surely they could scan it with higher resolution? Maybe that's the problem? Film scanned at 6400dpi should be about 8300 pixels wide. File you got will print only 6x4 at 300dpi. You'd probably be better off taking photos of the film with K20D.

After sending Ricoh UK quote from page 90 of the manual:
How to achieve correct exposure with aperture ring not set to A:
1. set the mode dial to M
2. set the aperture ring to desired aperture
3. press green button, the correct shutter speed will be set
4. If the correct exposure cannot be achieved adjust ISO sensitivity
I got another reply today:
