Interesting survey. In military terms, Russia is absolutely a paper tiger relatively to what Russia claimed to be before the war. Economically though, Russia has proven much more resilient than people thought (national comprehensive strength still heavily damaged though)
I don't think Russia itself ever claimed it had any insane capabilities. Its all projection from western chuds that played too much call of duty and watched too much of their own state media which is constantly playing up Russian threat by depicting Russia as capable of invading all of Europe in 1 week.
Saying that Putin not reaching Lviv in 3 days somehow represents that Russia was overrated means that your initial opinion of Russia was not founded on any sort of reality. Neither China or US would have been able to either, although because of massively greater gdp/industry, better air force and more precision weaponry, they could possibly get it done in a couple of months.
Overall, they perform more or less what you expect from an economy of that size. Basically tech/equipment wise they are an UK or Germany (which is obviously not world class but not omfg levels of bad), but because of having a large population, they're able to create larger armies than UK. They're also getting a boon from soviet stockpiles, same as Ukraine is doing.
