If you ask me "do I give credibility to the figures I post", I will send you here:
Today the official killed / missing in action figure for the Ruzzian army has reached half a million. Figures in war tend to be only estimates, but it is still a dam big estimate.
So I do give some degree of credibility to figures:

~516.080 +1080

Vehicles:
Russia - 16199, of which: destroyed: 11633, damaged: 733, abandoned: 924, captured: 2909

But you can also go to any more official source, they all assume between 465000 / 510000 loses.
Claims that Ukraine is loosing up to 50k soldiers/month were published in response to your claims, for a full picture. I give as much credibility on Russian losses coming from the Ukrainian side, as I do for Ukrainian losses coming from the Russian side. It's hard to imagine any more biased sources than direct participants in the conflict. In fact it's kind of their job to lie to their population in order to keep morale from collapsing. But logically speaking citing such information from the involved party is just pure propaganda. But I think it's safe to say that the side that has almost daily air alerts all over the country, countrywide power blackouts, loosing land daily, mobilizing younger population, support of who's leader is dropping, and who's leadership's existence is totally dependent on the direct support from the outside, has few more reasons to exaggerate. In other words, who do you think is more dependent on public opinion, guy who's daily job is to fight for every pair of eyeballs, trying to gather as much publicity as humanly possible in order to bring as much attention/support to Ukraine as possible, or well...Putin?
