So what you are saying is you developed this with classified material, contrary to ED's statements than all their modules are built on "publically available" documents and data?
Regardless, I do see the points some people are making. Intake geometry and aircraft weight do indeed affect overall performance, speed has a mostly linear effect on TSFC and should increase in low decimals between Mach numbers of 1.6 - 2.3 (roughly speaking from what I could find).
With this being based on non-public information and performance charts I can't really make my case here as I don't have a reliable reference like I do for the F-16C (HAF manuals). On the same note, the developer can also claim whatever they want since they have the "real manuals" and data and we have to believe them somehow? The entire reason I conducted these tests was because I had a discussion with some people saying the JF-17 was more fuel efficient than the F-15 or F-16. There is also no FF gauge in the JF-17 which makes manually plotting any perf charts pretty much impossible for the scope of DCS.
