The Russians are currently preparing for the second invasion of Ukraine. In reading up on Russian mobilization, it appears that they will continue to collect people into November. So the anticipated 'winter offensive' with up to half a million men will be slated into 2023. The unlucky conscript class of 2022-2023 (130,000 young men, a decrease of 30,000 from 2021-2022- odd?) would also be training. So this group of reservists will be somewhere under 300,000 men in addition to the 70,000 volunteers already collected.
The Russians claim that they have already collected 220,000 men. If they manage to reach their 300,000 target by December 1st that means that the reservists will have to conduct various layers of unit (platoon, company, battalion, brigade) training. The 70,000 volunteers on the other hand have been collected since the beginning of the war and should be more advanced in their training. There were also some separate volunteer units being spotted in the Ukraine already.
As for Round 2 of this war, I'm thinking late winter at the earliest or early spring.
