Indeed. Asking them if the sky is blue would probably result in a request for access to your hub to "tweak" your wifi settings.

Well it has been over 3 years since I had a PT, or even a tech for my residential broadband. So I may be a little out of date on the job titles.

The above levels look good. Smack in the middle of the range for both downstream and upstream. Which is where you want them.

Looks worse than the first set, with downstream power that is borderline and lower SNR.
Downstream will be 3 dBmV lower because of the splitter.
It's worse to have low downstream power than high downstream power. So I personally wouldn't want my downstream at those levels, even though theoretically it's just about in spec. You're inviting lots of post-rs errors.
You just need the tap changed at the cabinet to get the downstream higher.

You're just pushing up the downstream power with the yellow brick, but not affecting the upstream. Which is the opposite of what you want. The yellow brick has to go!

No. What probably happened was that some engineer made a change in the network which caused your downstream power to drop, or maybe there was/is a temporary/intermittent fault.
Your old set top box could be the problem. If it's babbling noise.
It's also possible a tech just swapped your tap at the cabinet so he could connect a new neighbour up.
Instead of getting the problem fixed the normal way you've made things worse.

p.s. Looking back at your original low SNR values around 32/33 dB...
Make sure all coax connections are tight with a plastic spanner. Finger tight may not be good enough. It's possible to cause your own SNR fault if not. Which can happen intermittently.

3 years ago it took me 2 additional tech's after the installer (who left the levels out of spec) to get my levels right. The second tech was very friendly and knew what he was doing. It was no issue for him to change the tap. Just explain the situation that you get low downstream power levels sometimes and drop outs and would he mind..
JB will no doubt cringe at such advice.
