There is a +2 IPCs for 1A/1D pts.
The second hit cost + 6 IPCs.
But it doesn’t work anymore from a statistical point of view.
Here is the basis of my calculation:
Sorry for this long post everybody.
You can only read the first part to know my conclusion and past over the calculation.
Second part is to give proof of my assumptions.
I made it because I was pretty amazed by all the results.
I thought everyone interested in G40e cost calculation/structure should know.
@Baron:
@Uncrustable:
It was also a pretty uniform agreement that 7,8,10,16,18 is best for gameplay purposes.
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. :-o :-P :roll:
And it doesn’t change the balance cost of Cruiser:
0.537 * 19 IPCs/BB = 10.2 IPCs/CA, rounding down: 10 IPCs
Nor it changes the balance cost of Destroyers:
0.435 * 19 IPCs/BB = 8.265 IPCs/DD, rounding down: 8 IPCs
I have done other calculation of Battleships vs Carrier with 2 Fgs and 1 Fg+ 1 TcB.
At my own surprise, the results give something different than KionAAA maths.
And it shows that my intuition was right when I said, to keep overall balance between warships:
lowering by 2 IPCs cruiser & BB cost imply a -1 IPC to carrier also.
In summary, to get a statistical balance sea combat (assuming TcB is at 10 IPCs):
if BB cost 18, then Carrier must cost 35-20 (2 Fgs) = 15 IPCs,
if BB cost 19, then Carrier must cost 37-20 (2 Fgs) = 17 IPCs.
The maths follow below:
13 Cvs+26 Fgs vs 28 BBs = 50% vs 50%
13/28= 0.464 Cv/BB 28/13= 2.154 BB/Cv
2.154x18= 38.77 IPCs/Cv on offence
0.464x36= 16.7 IPCs/BB on defense
19 BBs vs 11 Cvs+22 Fgs = 50% vs 50%
19/11= 1.727 BB/Cv 11/19= 0.579 Cv/BB
0.579x36=20.84 IPC/BB on offence
1.727x18=31.09 IPC/Cv on defense
Average cost of Cv+2Fgs= (38.77+31.09)/2= 34.93 IPCs
Average cost of BB= (16.7+20.84)/2 = 18.77 IPCs
Same units different costs:
13 Cvs+26 Fgs vs 28 BBs = 50% vs 50%
13/28= 0.464 Cv/BB 28/13= 2.154 BB/Cv
2.154x19= 40.93 IPCs/Cv on offence
0.464x37= 17.17 IPCs/BB on defense
19 BBs vs 11 Cvs+22 Fgs = 50% vs 50%
19/11= 1.727 BB/Cv 11/19= 0.579 Cv/BB
0.579x37=21.42 IPC/BB on offence
1.727x19=32.81 IPC/Cv on defense
Average cost of Cv+2Fgs= (40.93+32.81)/2= 36.87 IPCs
Average cost of BB= (17.17+21.42)/2 = 19.3 IPCs
Vs Cv+ 1 Fg & 1 TcB
14 Cvs+14 Fg&TcBs vs 26 BBs = 50% vs 50%
14/26= 0.538 Cv/BB 26/14= 1.857 BB/Cv
1.857x18= 33.43 IPCs/Cv on offence
0.538x36= 19.37 IPCs/BB on defense
39 BBs vs 19 Cvs+19 Fg&TcBs = 50% vs 50%
39/19= 2.053 BB/Cv 19/39= 0.487 Cv/BB
0.487x36=17.54 IPC/BB on offence
2.053x18=36.95 IPC/Cv on defense
Average cost of Cv+1Fg&TcB= (33.43+36.95)/2= 35.2 IPCs
Average cost of BB= (19.37+17.54)/2 = 18.46 IPCs
Same units different costs:
14 Cvs+14 Fg&TcBs vs 26 BBs = 50% vs 50%
14/26= 0.538 Cv/BB 26/14= 1.857 BB/Cv
1.857x19= 35.28 IPCs/Cv on offence
0.538x37= 19.91 IPCs/BB on defense
39 BBs vs 19 Cvs+19 Fg&TcBs = 50% vs 50%
39/19= 2.053 BB/Cv 19/39= 0.487 Cv/BB
0.487x37=18.02 IPC/BB on offence
2.053x19=39.01 IPC/Cv on defense
Average cost of Cv+1Fg&TcB= (35.28+39.01)/2= 37.14 IPCs
Average cost of BB= (19.91+18.02)/2 = 18.97 IPCs
