I'm very sceptical about such information. As said above they destroyed only about 10% of russian military equipment.
I don't know how reliable these numbers is, but there was 150 000 - 190 000 troops by the boarder. 90% of them is already in Ukraine. As reported by Ukraine, over 12000 were killed, over 30000 were injured or taken as POW's

I am as well sceptical, the numbers you provide are nearly impossible to verify but seem not possible. It is just a question of time, it is difficult to loose that many resources in such a little time and does not match past war experiences in comparable scenarios.
What I do believe is that Putin miscalculated quite a few things: the resistance of Ukrainians, the speed and size of the world's response and, and this why I published the post, the state of his own army.
No air superiority to be seen, slow advances if any and, lastly, having to resort to bomb the cities despite civilians, temerity or even plain incompetency by fighting near the nuclear reactors,... That does not look like an overpowerfull, almighty, well supplied and high morale, technologically superior army at all.
