Brick wall Calculation

Rook. Your sure about that 465+20*(x+y)?
Hoped I did not have to look into this (As I generally suck at math). But I also end up with 505+20*(x+y).

(minimal wall design.)
*-*--*-* [295] (50*2:CP-corners)+(50*2:CP-gate)+(75:gate)+(10*2:wall) = (50*2)+(50*2)+(75)+(10*2) = 100+100+75+20 = 295
|      | [_20] (10*2:wall) = 20
*------* [160] (50*2:CP-corners)+(10*6:wall) = 100+60 = 160
        +[250] AICP
	=[725] (295+20+160+250=725)

walls: 6+2+2=10,10*10=100
gate: 175
corners: 200
AIPC: 250 (Additional Initial Counterpost construction cost.)
100+175+200+250=725

Base CP cost
- +250 AICP
- 200 Corners(only).
- 175 gate(total).
(625) (250+200+175=625)

with 8+3: (22=11*2)
- 220 (10*22)
- -40 Double wall counts. (for each corner(10*4))
= 180
-  -80 Double wall/CP counts. (for each corner(10*4) + Gate setup(10*4:2CP+Gate=2) = 40+40 = 80
= 100
(725)=(625+100)
(8+3)*20-120+625=725 (120=40+80 = Double counts, all)
625-120=505
(8+3)*20+505=725

Rook is right.

Each corner is counted twice since of them being counted in both the x and y, so it's -20 for each corner (then -30 between the gate and fifth cornerpost), totalling a subtraction of 110 from 575.

Also your example is warped terribly. It's 300 bricks for the ICP, and it's created acting as if we create 2 cornerposts for the gate, when the formula made was for one of the gate's CPs to be a corner.

Seems a important part of the IPC var I used got ditched in the copy and past. But it needs to be seen as the 'Additional" cost over the general Conterpost cost. So it can be used as seperate math item. (Ergo: I ::split the ICP into a AIPC and CP part, Just kept calling it ICP. That's all). (I'm not convinced. Where it the error in my math?) --MvGulik 12:11, 25 March 2012 (EDT)

Yeah, Rook's formula works I think. I use

(300+CPS*50+GATES*75)+20*(X+Y-4)-(CPS-3)*10-GATES*20

for my calculator now.

(300+CPS*50+GATES*75)

Base cost for subsequent CPs and initial CP and gates

20*(X+Y-4)

The cost of all ordinary wall tiles, discounting the corners

-(CPS-3)*10-GATES*20

We previously used the cost for wall tiles that might actually be gates or CPs, so we compensate here.

It would be embarrassing if this calculation was wrong.

It should also be said that there is some value in verbosity, even though it might scare some people away, it is easier to follow something verbose. --ArvinJA 12:20, 25 March 2012 (EDT)
