Okay, I see what you were trying for there, now, here's my counter argument:
"Improved" cockpit
6 tons
6 crits
reduces the impact of cockpit hits to the pilot by one, improves consciousness checks by two, improves shutdown/overheat checks by two, PSR by 1.
Reasoning:
Better ergonomics for the pilot, better insulated cockpit electronics, redundant life support systems, improved cockpit ventilation, better cockpit seating and straps, and overall safety improvements to keep the pilot in the fight longer.
Thus, NOT infringing on Targeting Computers or other systems. The 'improvement' means you're more durable, less likely to be knocked out, with better protection against the 'transfer hits' caused when the head gets hit with a non-penetrating weapon.
That CAN be worth two and two on tons and crits, esp. on something heavier and more expensive.
