After further thinking, the cost for "missiles" must be for
missiles as a _group_ and not for individual missiles.  Correct?

STUPID QUESTION SEVEN:  But where does the "3 for a one-in-three
chance to damage treads" come from?  This seems exactly opposite
from the OS factor in the Armor Units Formula (which would be
0.333 in this case).

     I still don't get this . . .  I suppose that if I want to
     make this fit into a version of Henry's equation, I could
     get the value "10" with:

          ((dice damage done * 3.5 average roll) / OS ) etc.

     OS = one-shot factor, 1.0, except for one-shot weapons, where
          it's 0.333.
     This gets the OS factor into the ramming cost equation and
     still have the numbers come out correctly.

cost = direct cost + load cost
     = [(Atk * (Rng + OR)) + (2 * Def * Rng)]
          + [(Atk * MM * ½) + (Def * MM)] * X

missile (6/5, D3)
     = [(6 * (10 + 0.333)) + (2 * 3 * 10)]
          + [(6 * 1.4 * 0.5) + (3 * 1.4)] * X

     = direct cost of 112  +  [load cost of 8.4] * X

converting "henries" to VPs by dividing by 12, this gives:

     = direct cost of 11.2  +  [load cost of 1] * X

Damn it!  I still can't get what Henry got!  Where
am I going wrong?
