I can not say that I am surprised by this..
Over the past 10 years of flight simming I have noticed this tread of not caring about how accurate the flight model is in simulating the aircraft performance..
Which is not surprising what with all the arcade style (xbox) types of flights simmers that have come along in the past 10 years..
Where they are more concerned with eye-candy than the flight models ability to accurately simulate the aircraft performance..
The good news is..
With time..
Some of these xbox type evolve (grow up?) into what we use to call a 'hard core flight simmer'.
Where getting the performance right is not an option but a 'basic' requirement.
The evolution of the xbox mind set typically goes like this..
They start off not caring at all about the accuracy of the flight model to simulate the aircraft performance, to caring about the 'relative' performance of the aircraft, to finally caring about the flight model being able to simulate the aircraft performance within 5% of the real world data.
Sadly some never make the full transition and are happy enough with something less than accurate..
Which is why flight sim makers always have to provide enough options to convert the accurate flight simulation into an xbox arcade type of game.
