Replacement rate for frontline units in WW2

[Aeraaa]

Slightly off topic question, but can anybody show me a link describing replacement rate for say a division in WW2? I know that this differs from branch to branch (infantry probably suffering more casualties than artillery) or country to country, but if anyone could show me a document telling how many days it took for a combat unit to replenish it's manpower I'd be much obliged.
