Having the actual historic range would imply your missions ran the actual historic ranges. Most airfields are 1 sector apart. Sectors are only 25 miles square.
You want historic fuel, make it so you have to fly 2 hours before seeing the enemy. Oh, wait, people won't pay to do that in an MMO flight sim.
If you're interested in historic ranges try historic throttle settings (read: not FFS).
I regularly take 100% and DTs in 190s of all types, and I usually can fly around (assuming I'm not killed early on!) for 40-mins and more on internal fuel only, including multiple engagements that require WEP. This is in the MAs with 2x fuel burn.
If your mission ran 2-3 hours long, it's your own fault for not getting to the point faster. If you ran out of gas in under 30 minutes with 100%+DT you didn't take full fuel in any 190 variant. Even if you ran full WEP as much as you could as long as you could, the 190s with DTs will still give you over half an hour of full throttle. This increases GREATLY by easing back off the throttles by the smallest margins.
