I wonder though if there is some scientific research that can be pulled up referencing racial characteristics and the ability to cope with G forces. Point being if the Japanese pilots could take G forces better than their typical Caucasian adversaries than maybe HTC could accommodate for that and allow the Japanese fighters another 1/2 G before blackout? That is just an example. Same goes for the Russians and their fondness of vodka, maybe since their blood was typically thinned a bit they would not be able to handle the G's?

Otherwise... this would be far too difficult for HTC to implement. Also, this hold about as much water as emptying out the rear gun on the 110 "to make it turn better".
