Well here's my mathematical analysis of the problem.
For sake of brevity I will only deal with a non existing weapon.
In the table below
WP= Weapon Power
RoF= Rate of Fire
PpS= Power per Minute
AP = Applied Power
--------------------------------------------------------
WP.....RoF.........PpM.......%Hit...AP........%Pow er
1 100....700.........70000....4%.....2800....100
2 110....700.........77000.....4%......3080.....110
3 100....700.........70000.....5%......3500......125
---------------------------------------------------------
In line one we have a generic weapon with a "power" of 100 and a RoF of 700 rounds per minute. Historically pilots scored an average of 2 - 5% hits so I've taken a baseline % hits as 4%. This means that 2800 units of power have been applied to the target which is 100%Power.
Line 2 assumes that the code is altered by 10% and power on target increases by 10%
Line 3 assumes you can increase your accuracy by just 1% this means that an extra 25% power is applied to the target above the standard score.
To get the same increase of power applied to the target at line 3 you would have to boost the weapons power (in the code) by 25% over the standard power.
Now if all the time and energy that has gone into arguing the case for changing the weapon powers had gone into gunnery practice, this issue may not have existed in the first place

warped logics or Excel in the hands of a Chart Monkey is a very dangerous thing!
