Often the numbers quoted for maximum range by various sources were either theorectical or obtained by testing under optimal, not wartime, conditions
Actually, this is not the case. Almost always maximum range is cited in typical configuration. Almost any large plane can greatly exceed that by special measures - and routinely did. Joe cited cases where US bombers flew missions much greater than the game allows - but they stripped armor, carried ferry tanks - etc - something we cannot easily simulate. Reference books do not usually give true maximum (ferry) range - they give the ferry range for a typical configuration as delivered - which is quite a bit less than what is possible. The Condor flew OPERATIONAL missions FARTHER than its reference book FERRY range - ARMED no less - by the expedient of carrying 55 gallon drums of fuel - and hand pumps!
I believe they carried 1 gallon gas cans on the Doolittle raid too. Lots of ways to change the book value, and not always for ferry missions.
