Not that this deserves a serious answer but...
Russia has lost a tiny fraction of its available for combat manpower, albeit they've lost a good percentage of their best trained and best experienced personnel, but then more will be gaining significant experience through the Ukraine war - there is no substitute to lessons learned in real combat. Even the poorer far east regions they've been heavily pulling man power from they've not exceeded around 10% of the reserves, in most regions that is still below 1%. If Putin goes down that path they can still mobilise world war levels of man power.
I think you need to look at this not from an army manpower but a nation manpower. If this is 10% of 10% then 1% of a nation being lost is a rather large deal. Now I could work out the details but it's probably in the 0.1-1.0% range at the moment. That's 0.1-1% and the nation's economy is close to breaking point. The nation has a history of revolution once a threshold that the serfdom can't tolerate.
