:::Because Raul Hillberg (The Destruction of the European Jews) gave an estimated total death toll of 5.1 million Jews,  
 :::R. J. Rummel ('Death by Government', Pg 10, Table 1.5) gave an estimated total death toll of 5.2 million,  
 :::Reitlinger ('The Final Solution') gave an estimated total death toll of 4.2 to 4.5 million, 
 :::So we could argue that if we want to be verifiably accurate using ALL these reputable sources that we should have a sentence that says "between 4.2 to 5.29 million"
