Since launching a surprise attack last week, Moscow has been unable to push Ukrainian troops back after they advanced up to 30km into Russian territory and are now in control of about 28 settlements.
Russia has undeniably made gains. Avdiivka is comparable in size to the Russian territory taken by Ukraine. Except it took Russia a year and 30,000 casualties and hundreds of armored vehicles losses. Ukraine's push into Russia has happened over days and Russia still hasn't pivoted with a coherent response.
