First of all ordnance leader damage bonus applies in the end of all damage calculations after all reductions are done.
Second, Barrier Shield strength is 60 atm, was 64 before and 56 before 64.
Ah, nice to know, i havent followed the last changes in Barrier Shield absorption (i dunno why it was changed anyways, the difference is quite little enough)
That the damage-bonus applies in the end is completely new to me. I thought, that the damage boni are applied the same way as high-energy focus for beams do. I will check this and be back in some Time.
Edit:
Check done, my memories were nearly right. The damage boni from leaders are count exactly the same way as High-Energy Focus and modifications like Heavy-Mount are done. I just forgot, that Overloaded are calculated the same way as Heavy-Mount as well.
!!! IMPORTANT !!!
THE LEADER BONI APPLIES BEFORE ABSORPTION IS CALCULATED !!!
I will explain:
(((Basic Damage * Damage Modifier) * Target Modifier) - Absorb) * Number of Hits = Damage Done
Usual after calculating values in () The Number is rounded up afterwards and the rounded number is used for further calculations.
Damage Modifier are added together
There are these Damage Modifiers:
-50% for Point Defense
+50% for Heavy Mount
+50% for High Energy Focus
+50 for overloaded (exactly the same as for heavy mount)
+x% For leader
All Boni are added together, NOT multiplied!
Example:
If a battleship without leader fires a heavy-mount disruptor with high-energy focus against a Shieldclass 26 Barrier-Shield the Damage done is this:
Basic Damage for disruptor = 80
Modifier: +50% for Heavy Mount, +50% for High Energy Focus: +100% (additive boni) = 2
Target Modifier is -50% for Hits against planets = *0,5
Absorb Modifier is 60 For Barrier Shield and 26 for Shieldclass 26 = 86
Damage Done is:
80 * 2 / 2 - 86 = -6 -> 0 Damage Done
If Loknar (Damage +37%) is commanding the Battleship the Damage Done modifies this way:
Basic Damage = 80
Modifier: +50% for Heavy Mount, +50% for High Energy Focus, +37% for Leader: +137% (additive boni) = 2,37
Target Modifier is -50% for Hits against planets = *0,5
Absorb Modifier is 60 For Barrier Shield and 26 for Shieldclass 26 = 86
Damage Done is:
(((80 * 2,37) / 2) - 86) = 9 -> 9 Damage Done. If the HV Disruptor was Autofire, the Damage would be 9*3=27.
As you can See, damage modifiers from Leaders can lead to situations, where weapons still can do damage where ships without leader Boni would always do 0 Damage!
Back to the Torpedo Problem:
Basic Damage= 266
Modifier: +50% Overloaded = 1,5
Target Modifier: -50% = *0,5
Absorb Modifier: 60+26 = 86
Damage Done without Leader:
(((266 * 1,5) /2) - 86 ) * 4 = 456 Damage Done
Damage Done with 20% Leader:
(((266 * 1,7) /2) - 86 ) * 4 = 564 Damage Done
Damage Done with 30% Leader:
(((266 * 1,8 ) /2) - 86 ) * 4 = 616 Damage Done
Damage Done with Loknar (37%)
(((266 * 1,87) /2) - 86 ) * 4 = 652 Damage Done
Sometimes the Game rounds up or down in odd ways after calculating parts of the formula (i usual round up after calculating the basic Damage * damage modifier to get best results) so the Damage could differ some Points, but general the Damage Done should be exactly this. If the Enemy would have used a 30% Leader, the dual Torp Hit shall be 1232 Damage.
