You are cherry picking statistics. If you’ve ever played with both missiles (which I have) you’ll find it quite obvious that Hellfire has better speed and responsiveness. For reference, these are some that you missed.
Some parameters from the same document to highlight:
1. Raw acceleration.
Hellfire wins easily with 151.33 m/s^2 vs 119.57 of AKD-10. It gives the Hellfire much more starting energy.
2. Booster vs. Overall delta V
The Hellfire has a much stronger booster than AKD-10 with 501m/s vs 122 m/s of AKD-10. Although AKD-10 has a strong sustainer while Hellfire lacks one, in practice, their traits mean that Hellfires will be much faster to hit targets of typical ranges (less than 6k meters, common when spawning at closest helipad in GRB).
3. Maneuverability.
It is true both have same G load and wing area multiplier. However, consider that the AKD-10 is MUCH heavier than the Hellfire. After the booster burns out, which is 3 seconds for the Hellfire and 1 for AKD-10, the Hellfire weighs 36.8 kg while the AKD-10 weighs 43.5 kg. That’s 118% heavier. The sustainer of AKD-10 takes 23 seconds to burn off, and even after that, AKD-10 still weighs a comparable 35 kg.
As well as being heavier, AKD-10 is considerably slower at <6km ranges than Hellfires, as we’ve established already. It also lifts less, at 8 degrees vs the 9.6 of Hellfire. These factors mean that it will have less energy to maneuver with.
Combined with the wing area multiplier, which is a bit lower, this results in the AKD-10 being much less maneuverable. Especially at typical Ground RB engagement ranges.
If you’ve ever used both missiles, you can feel the difference quite easily. Hellfire has MUCH lower time to target compared to AKD-10.
