found an article while looking up stuff about how its more point efficient to spend BP on a smaller ship's ac and how Larger Ships get screwed.
So i decided to write up and Excel Formula that goes something like
BP Cost at AC Value([(AC Value - Size Value)+1])* Size Value
Where Size Value is Tiny=1, Small=2, Medium=3, etc...
and BP Cost at AC Value is like how AC1=1, AC2=2, AC3=3, AC4=5, AC5=7, etc... as shown on Page 297 Core
This means that a Colossal Ship gets AC6 for 6 BP while near the end of the game a Tiny Ship would still get AC15 for 45, but now the Colossal Ship is getting AC15 for a more manageable 126 BP
Issues i am having with this formula is that some values for smaller ships at lower AC's end up costing more then for larger ships. As soon as someone shows me how to enter a Table, I'll Post the Values i came up with
Finally, BP Cost at AC Value()
is like Function of G or f(g)
Excel File for New Calculations
Changed Formula to f(g-Floor(h/2))*h
Where function is in terms of the BP cost per Level of AC
g is the level of AC
h is the Size Value
This gave a more steady curve which felt better
So Larger ships get a higher base line AC then Smaller ships at the same pricing early on, but not for larger AC Values
Other thoughts on the Subject,
have AC grant a bonus on the Damage Threshold for Huge and Larger ships equal to AC Value * (Size Value - 4)
