It seems that Dima of "The Military Summary Channel" - https://www.youtube.com/@militarysummary/videos - is a German guy who is doing some of the best projecting of what is actually happening on the ground. In addition, he has enough experience that often he projects his own ideas into what is happening. You would do well to take a look at his daily videos. Further, you would do well to look at the comments for each individual video.
I've seen plenty of channels which analyze maps and what's happening in front lines. But I prefer channels which are trying to stay neutral. While this one in probably 90% cases is only showing what's happening in one side.In post above you said that Russia is making strong advance. That's not true and in general it's almost impossible to makebig advance now. Something like we saw in first days of war when Russia took most part of what they now, or Ukraine's Kharkiv or Cherson counteroffensive. There is good analysis, in Russian, but Telegram app have good translator:

Mainly it's all about drones - FPV and surveilance. Everything is under control what makes any significant movement complicated. Only Russian meat grinder tactics let them to advance not significantly and without counting losses of people and equipment.
I'm not anywhere where I can confirm which channels are correct. So, I have to move on to the important point.
Do you remember Russian Oreshnik used in Dnipro November 21 last year? A new form of ICBM with 6 warheads that weren't armed, but did damage simply by hitting the ground... mach 10.5.
Then, 2 or 3 weeks ago, Kiev struck Moscow, and I thought Putin would use Oreshnik in retaliation. So, I warned people to leave Kiev. Putin didn't use Oreshnik, but did tons of damage with missiles and drones.
Now, Germany is sending Taurus missiles to Kiev to strike within Russia. Russia has threatened Oreshnik retaliation on both, Kiev and Berlin.
Here's the stickler. Even though Putin has been manufacturing Oreshniks, Russia doesn't have a lot of them, yet. So, what is Putin going to do? Will he use unarmed Oreshniks like he did at Dnipro? Will he waste his resources like that?
Kiev, and now Germany, have been pushing Russia into a corner. Russia almost doesn't have any choice except to use nukes.
Europe is playing with dynamite. If I were in Kiev or Berlin, I'd be moving as far from them as I could get... even if I had to lose my home and much of my property to do it. It's not worth dying for. I can start over elsewhere.
