I am 100% with you that Russia needs to be thrown out of Ukraine, In principle the only number high enough is what makes Russia give up and never come back.
But we also have to appreciate that Ukraine is actually successfully holding back a force 4 times their own size, and it is going better for Ukraine on the front 4½ years into a war where Russia has hammered Ukraine as hard as they can, and Russia is beginning to lose terrain despite increasing their efforts.
This is a result of an enormous effort by Ukraine and aid from their many allies.
And what Russia is doing is IMO insane. It is insane that they accept these losses and continue their bu now obviously futile efforts.
I bet Ukraine is doing everything they can to get the numbers up. In fact that is allegedly part of a relatively new strategy since about March AFAIK, a strategy with the purpose of curbing the effect of an expected new Russian mobilization after the election, an expectation that seems to be justified.
