I'm guessing that's the 1.5mill cr one? What about your power plant? Perhaps for an A4 shield gen to show its full potential you need to upgrade that as well?
Nah. PP doesn't do anything except to provide enough power (or not) to turn stuff on or off. Mine is also an A4.
Disty makes a big difference to shield recharge.
...but beyond that, we absolutely DO NOT KNOW what the ratings on a shield mean. Many *assume* that bigger = better, but that need not be the case.
For example, it could be (completely arbitrary numbers for illustrative purposes):
E - 80% power, 20% recharge speed, 10T mass, 1.32 power draw
D - 85% power, 25% recharge speed, 4T mass (40%), 1.76 power draw
C - 100% power, 25% recharge speed, 10T mass, 2.20 power draw
B - 120% power, 20% recharge speed, 16T mass (160%), 2.64 power draw
A - 100% power, 30% recharge speed, 10T mass, 3.08 power draw
We don't even know (afaik) if shield recharge is
solely a factor of disty, or also of shield rating.
So yes, we could really do with some stats.
