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.
