I agree. This is a common trend for this time of the year, where all the usual movement and infiltration routes are suddenly very exposed due to falling leaves. This, combined with unusually intense Russian offensive operations, would naturally create such an effect. I expect the losses to begin to decrease over the winter.
Of course, as Playfra rightly points out, these numbers provided by the Ukrainian General Staff are exaggerated. In my opinion, the claims of 3k Russian victims per day (KIA + WIA) are a significant exaggeration. The claims that they have videos of all the FPV alerts are just claims, and there's no way to verify those numbers when we're only seeing a fraction of the supposed total.
And one should also ask, if Russia suffers such heavy losses due to these large and unusual offensive operations, then how many losses does Ukraine suffer due to those unusually large offensive operations, which are naturally supported by larger than usual offensive campaigns.
