I can not believe that there are people who do not accept right observations and dispute with phrases like: you are criticizing! you are not grateful to the ED! etc .. this is called being fanboy imho
If there are reliable charts it is reasonable to warn if there are inconsistencies that are not therefore based on "it seems to me"
Sorry for the outburst but for the last part. The flight model is not like armaments, radars, etc., the "enemy" knows the dimensions, characteristics, weight, etc., and through these is able to practice reverse engineering and know how an aircraft should behave in flight, so stop saying that because of a security issue they can't create a precise FM, if they can't, the reason is probably due to some technology that the "enemy" can't find with reverse engineering but not because you don't know the FM.
