An often repeated calculation in the lead-up to WWI was the fact that while France and Germany could complete their planned mobilizations (as in- getting every reservist slated to participate in their war various plans into his unti and to the frontiers) in two weeks, Russia could only complete said mobilization in six weeks.

To be sure, Russia ended up taking up offensive operations much sooner than Germany predicted (or it's own generals wanted, and with rather detrimental results Vs Germany) and found it's plans for supplying the troops it eventually mobilized sadly lacking. But the point is that the perception of the decision makers were that Russia's opponents had a short window of opportunity to defeat France before turning Eastwards and rebuffing

The dynamics of particular WWII made this less relevant- I have no Idea how long it took Germany to mobilize all the forces that participated in the conquest of Poland (Polish forces seem to have failed to complete mobilization before being overrun), and by the time the phony war ended all the major combatants were already mobilized.

Does anybody have any details regarding mobilization speeds OTL?

Absent WWI and the totalitarian regimes it spawned, and assuming all major polities survive in more or less the same alliance configuration (Russia-France Vs Germany-Austria with Italy and GB ambigiuous) what kind of gap is likely between the period Russia would require to mobilize for offensive operations in the Russian battle plans and German perceptions?

obviously, all other things being equal, the Schlieffen plan is scrap by the 1930s and probably much earlier. But still, what are the likely numbers?
