I am ready to change my position slightly (regarding usage of sliders at least), but I can not agree regarding status of Germany.
According to what I found
wiki and
holocaust encyclopedia in 1933 Jews constitued about 0.7% of German population - about 500000(and 20% of them were not even German citizens), and that number dropped to 200000 in 1939 and further 40000 emmigrated before 1941 when emmigration was forbidden. Even taking 200000 figure
we are talking about LESS than 0.3% of population!
So I have to strongly disagree that Hitler was killing substantial portion of his population. We could add communists, unionists, homosexuals and other "undesirables" but I think that total number would not exceed 0.5% - 1% of German population (my guess) - reading about Dachau I found that on average it hold 3000 Germans, and some of political prisoners were treated completely differently than Jews, Poles and Russians.
I could bet that Stalin killed higher percentage of his population in gulags.
And so we have to define what "your own population" means. IMO after Barbarossa Hitler did not capture any "his own territories" nor much "his own population". True that some Germans lived in Baltics, but according to the Ribbentrop-Molotov treaty they should migrate to Germany within 2 months (and my grandmother was deported (among other things) to make place for Baltic Germans).
I am not an expert on Estonia but I could say: Yes, Germany conquered Baltics, including Estonia. But did Hitler promise Estonians independent Estonia? They did not want to fight for Soviets (after what happened when Stalin annexed Estonia) and defected. It seems to me that with so low German input Hitler got quite good number of people.
So Germans excluded/exterminated few hundred thousand of their citizens. On the other hand Germans created
Volksliste - granting different kid of priviliged status. According to previous page it were over 3 million people, thus order of magnitude more than number of Jews.
In my books it counts as "using many kinds of people" (especially adding all those "too late" additions you have ennumerated).
So the eventual German modifiers should be: 0.995 in Germany and nevertheless quite positive factor in occupied Poland, and smaller one in Baltics and other regions.
IMO 0.995 could be represented as 1 for all practical reasons. This why I would leave German manpower in Germany unmodified but reduce South African, USA's etc at the same time.
Edit: depending of assumed timeframe and type one could count number of Stalins' victims among his own population as high as 10 or even 15 millions (with overall population 100 million in 1930 and 108 million in 1939). Even if we exclude victims of famine in 30-ties (which were result of Stalin's policy) we still get 5-10% of population.
Edit2: Wrong figure: those 100/108 millions were for Russia alone, Soviet Union in 1939 had 168 millions, so we get sth between 3% and 6% (and maybe up to 10% with famine victims)
