All I can add is the really good players like Treasurer, Quaxocal, Blueserpent and others work out stuff by brains, trial and error and however else they do it. Giving formulae to us all just reduces the difference between understanding the game and merely playing it. Jo, I think the formulae are way to complex to actually work out exactly by trial and error, but my point was having exact formulae would make it possible to come close to ideal for everyone regardless of "the skill comes with balancing the way in which all the aspects interrelate and affect each other,"
Anyway, I'll shut up 'cause I really dont care atm, I just like discussing stuff with the more intelligent patrons of the game.
