I really do not want to get into another debate about this. So, I'll summarise and then stop posting in this thread:
1. Operational pilots frequently say that they are unable to achieve the performance that the EM charts say they should. Hence, the comment about fantasy. A very simple example: a friend who was an F-15C pilot and flew functional check flights told me that he NEVER managed to get an F-15 to go anything near the Mach number the books said it should have.
2. EM graphs are built using factory-fresh aircraft and factory-fresh engines. The operational fighter pilot will typically see it as simply an illustration of what may be possible
3. Who is to determine what is "accurate" or "unbiased"? If someone who flew the F-15 tells me that the EM diagrams didn't match the reality, I am going to believe them, particularly if this view is widely shared by those who have done the job for real (and I will tell you that, in my experience, it is).
If you want to actually hear a fighter pilot talk about what the books said and what the aircraft could do, take a look here (books M1.25, reality M.95):
