[Pre-BB] MapleStory Formula Compilation

Battleship Durability: (Battleship level * 2 + (Character level - 120)) * 2000
Each point of durability is equivalent to 1 HP.

So with this, old battleship formula at level 181 with maxed ship (10) gives me 162,000 hp. After the last update to GMS I just quickly tested the ships HP and it seems to be definetly over 230,000 hp. I was able to take 177x-18xx dmg for 130 hits before ship broke.
So the formula maybe something like (Battleship level * 5 + (Character level - 120)) * 2000 or (Battleship level * 6 + (Character level - 120)) * 2000. Thats just a guess, maybe its a change in the character level part of the formula.

I get the formula is
BattleShip Level * 5000 + (character level -120) * 3000
I logged the damage each time the mobs hit me.But at last I disconnected....
while I dropped, the sum of my log is 218599 and the icon of skill righttop has flashed a few time.
Then I make up a sheet to find out the a,b in
BattleShip Level * a + (character level -120) * b = 1000 * C
C means Battleship Durability.

BattleShip Level =10, character level = 178
a=5,b=3,c=224 is suitable because all of them are integer =w=
While the old formula is a=4, b=2.
