12 DDs A2 = 17 SS D1, 50% vs 50% it is a fair and even fight.
.71 DD A2 = 1SS D1
(.71 DD/SS * 8 IPCs/DD) = 5.68 IPCs/Sub, it means that 7 IPCs Subs are too high cost, it should be 6 IPCs.
Let’s try 6 IPCs Subs: 1.42 x 6 IPCs = 8.52 IPCs, that should be the balance cost of DD on offence (near a 8, so it is OK).
1 SS A2 = 1 DD D2, 50% vs 50%
7 IPCs better than 8 IPCs.
Subs are better on offence but only against warship, cannot hit air units. Seems OK.
But the A2 of Subs is less powerful than A2 of DD against warships with DDs.
But it is difficult to ponder how less powerful?
Yes its a conundrum because subs have a different attack on offense and defense.
Maybe with the other cost changes subs will be less powerful anyhow, and leaving them at 6 is the best option
35 cruisers A3 (D3) vs 43 Destroyers D2 (A2) = 50% vs 50% on the battlecalc.
35/43 = 0.814 CA/DD 43/35 = 1.228 DD/CA
0.814 * 10 IPCs/CA = 8.14 IPCs/DDs, rounding down: 8 IPCs
1.228 * 8 IPCs/DD = 9.824 IPCs/CAs rounding up: 10 IPCs
To prove that the maths balance cost of Battleship unit should be 18 IPCs vs Destroyers:
20 Battleships A4 (D4) vs 46 Destroyers D2 (A2) = 50% vs 50% on the battlecalc.
20/46 = 0.435 BB/DD 46/20 = 2.3 DD/BB
0.435 * 18 IPCs/BB = 7.83 IPCs/DD, rounding up: 8 IPCs
2.3 * 8 IPCs/DD = 18.4 IPCs/BB rounding down: 18 IPCs

To prove that the maths balance cost of Battleship unit should be 18 IPCs vs Cruiser at 10 IPCs:
22 Battleships A4 (D4) vs 41 Cruisers D3 (A3) = 50% vs 50% on the battlecalc.
22/41 = 0.537 BB/CA 41/22 = 1.864 CA/BB
0.537 * 18 IPCs/BB = 9.67 IPCs/CA, rounding up: 10 IPCs
1.864 * 10 IPCs/CA = 18.6 IPCs/BB rounding down: 18 IPCs…
but surprise!!!, it could be rounding up to 19 IPCS!!!
So if someone want a less efficient but more historically accurate over expensive BB unit:
Battleship should be at 19 IPCs. shocked tongue rolleyes
That’s the cold math.
Great post.
I wish more people could understand this.
