Unit Cost Equation

[The_Tauren13]

Im moving this to a new thread so I quit hogging Scott Heberts excellent thread on Commander costs...

Heres my current formula for caulculating the cost of a unit based on (and only on) its physical stats:
sqrt(((HP*(10.0+Prot)*Def*MR)/1000.0)*((Str*Att)/10.0))*((3.0+Move)/5.0)*((40.0+AP)/50.0)*(9.0/(6.0+Enc))*((Mor^log10(7))/7.0)
Comments, anyone? Suggestions? Flames? Donations?

So, back to the morale buisiness:
Perhaps just a chart is the way to go, then.
I hate making morale 0-5 cost exactly the same, because there is a change, however small and imperceptable
Besides, there arent any troops with under 7 morale, are there? Theyd be useless, and Illwinter knows it

  13     1.90

  14     2.00

  15     2.09

  20     2.39

  21     2.42

  22     2.44

  23     2.45

  24     2.46

  25     2.47

  26     2.48

  27     2.49

  28     2.50

  29     2.51

  30     2.52

Now, the question is, if I do get this chart accurate, should it stay as just a multiplier to what the cost would be otherwise?
