i look at it simply. The total power of your vessel rating when you click on modules gives an indication of what your totals are at base value. That figure is what is reported to others as your power, and is used as a baseline to any npc mission pickup strengths as well as odds of completing missions, based on that base line.
The REAL numbers are what you see in the boxes above the total power, based on your modifications, tactical sciences and officers and its what you actually hit your opponent with.
so in reality if my odds of winning are 3:35 in favour of the bad guy, you would expect i would lose. However, with all my bonuses and combats, i actually win the day and fly away with the prize.
For eg, if i have a reported power of 1,000,000 vessel total yet my bonuses for that ship equate +85% all round on shields and weapons, then my real power is 1,850,000. factor in a dodge percentage gives you more numbers. (45% dodge, chance to hit 55%.....multiply 1.850.000 x 55/100 gives you an even bigger power base, in theory)
Still wondering how you got that banner in your signature.
it states that you can use BBC code in signature block. maybe look at that BB Goode
