{First maneuever AoA (Double) (2 attacks), Extra Attack 2 (+2 attacks), DWA (+1 attack); second maneuver Attack (1 attack), Extra Attack 2 (+2 attacks), DWA (+1 attack).}

He could have had allot more... "Dual Weapon Attack" is actually "number of arms weapon attack"

What keeps this under control is the GM's limit on Weapon Mounts (on a humanoid body, two is about the upper limit) and the PC's budget for weapons and ammo. And of course Dual-Weapon Attack, Extra Arms (Weapon Mount), and Off-Hand Weapon Training aren't free, and being able to engage lots of foes this way calls for Enhanced Tracking.

To compare to the real world: Imagine that the PC is the pilot of an attack helicopter with two Weapon Mounts on each side, on pylons under stub wings, and another in a chin turret. Raking the same target with fire from all five is entirely plausible. He points the aircraft to aim one weapon (at 0 to hit for the "master" hand) and all the others are sort of pointed there (at -4 for the "off" hand). Firing lots of weapons at once gives a further -4 (as for Dual-Weapon Attack) because it's distracting and hard to coordinate. Aiming the weapons individually is impossible without Enhanced Tracking in the form of fancy targeting computers, guided weapons, etc.
