Does the "Structural Ergonomics" equipment increase power recharge beyond 200%?
Solution 1:
Yes it does. Going over 200% however provides an extremely poor diminishing return, which is why the effect is barely noticeable.
Assuming that you are using Warp with 2 setups.
Warp level 6 with 200% recharge 8 / (1 + 2 + 0.25) = 2.46s
Warp level 6 with 205% recharge (structural ergonomics I) 8 / (1 + 2 + 0.25 + 0.05) = 2.42s
*Note that the 0.25 comes from warp's second level, increasing recharge by 25%.
