Exactly. See how you match the F-5 so closely? Now imagine you’ve forced him to waste some energy so he’s at a lower speed than you, now you have an advantage. Or say he pulls but not at his optimal rate given the real world conditions, you turn in more aggressive, maybe trade some energy for a harder turn, now you’re on his 6. That’s how a dogfight works.
Same goes for Alpha jet, he has a slight advantage for most speeds, but compresses before you and again…it’s not a huge gap. If you manage energy and engage in a smart way rather than just holding S and going into a horizontal rate fight. In the case of the troublesome Alpha Jet you’ve had issues with, you have more thrust at any speed than he does.
I’m not critiquing you to be mean or say you’re bad, just to say I think you haven’t spent enough time learning the AMX and its ability to punch above its weight class. Could it go down to 10.7? Yeah, but to say it sucks is genuinely absurd. I have a K/D of 3.28 in the AMX and I’m genuinely not a good player. The only jet I have a higher K/D in is the excellent MB326K at a square 4.0
