Unless Russia had resource and power to operate at peak level for the next decade, timeline is important.Now it fastened much, uaf is on the ropes in donbas. Goal of russians is to degrade and destroy as much is possible uaf combat capabilities and they do that, timeline is less important, for illustration what i am saying on last exchange of dead soldiers there was seven times more of uaf ones and that is clear indicator who has upper hand in war.
On the other hand, judging by the fact that Russia was not able to breakthrough at as hasten pace since Kursk incursion, I would say the activity level remain the same. Again, this is not the first week of the Kursk incursion, we are on the 3 week mark (It was started on the 6th) if there are exploit in the line, the Russian would already had took it and already ran away with it.
As for who had advantage on this? I don't know, if there are any advantage for the Russian on this, it wasn't reflected in the actual battle. On the other hand, if Ukraine did lose 7 times the troop, then either Russian troop is extremely poorly organised or extremely inept to not be able to roll back Ukrainian incursion 3 weeks down, you are claiming 7 times losses.
Again, any number in this war is not important, the only number that's important is how far did Russia made, and as I said, that number is not good.
