	~~Since~~ the intent is to have 50% of the penalty come from health and 50% from morale, the parenthesized versions should ~~read~~:		As you noted, the intent is to have 50% of the penalty come from health and 50% from morale. However, omitting the parentheses is technically accurate but misleading, because division is not commutative in general.

			The clear way to write the parenthesized versions should be:

	hp = (acc * (max.health - current.health) / max.health) / 2		hp = (acc * (max.health - current.health) / max.health) / 2

	mp = (acc * (100 - current.morale) / 100) / 2)		mp = (acc * (100 - current.morale) / 100) / 2)

	hp = acc * (max.health - current.health) / (2*max.health)		hp = acc * (max.health - current.health) / (2*max.health)

	mp = acc * (100 - current.morale) / 200		mp = acc * (100 - current.morale) / 200

			Eh...looks like a mistranslation.

			Since the intent is to have 50% of the penalty come from health and 50% from morale, the parenthesized versions should read:

			hp = (acc * (max.health - current.health) / max.health) / 2
			mp = (acc * (100 - current.morale) / 100) / 2)

			i.e.

			hp = acc * (max.health - current.health) / (2*max.health)
			mp = acc * (100 - current.morale) / 200

			== Ist the formula itself incorrect.? ==

			The lines
			:hp = acc * (max.health - current.health) / (max.health / 2)

			and

			:hp = 2 * acc * (max.health - current.health) / max.health

			are mathematically equal, but I'm really not sure if the formula
			itself is right.


			'''One Example:'''

			Accuracy=80

			max.Health=50

			current.health=25


			hp = 80 * (50 - 25) / (50 / 2) = 80 * (25 / 25) = 80 (!)


			This can not be right. If I understood it correctly, the hp can be
			the half of the total accuracy in maximum. In this simple case I did
			use, the lost accuracy iss 100%! Not mentioned, what would happen, if
			the morale is also low... Negative accuracy can't be possible.


			Isn't it right this way?


			hp = acc * (max.health - current.health) / max.health /2


			For the example I used:


			hp = 80 * (50 - 25) / 50 / 2 = 80 * 25 / 50 / 2 = 20


			For the mp it's the same:


			80 accuracy

			50 morale


			mp = acc * (100 - current.morale) / 50

			mp = 80 * (100 - 50) / 50 = 80 * 50 / 50 = 80


			'''I guess this is the proper way:'''


			mp = acc * (100 - current.morale) / 200

			mp = 80 * (100 - 50) / 200 = 80 * 50 / 200 = 20


			Am I wrong, or is there a mistake in this article :-) ?


			BTW: I think this formula style is OK:

			hp = acc * (max.health - current.health) / max.health / 2

	Well, these can. My problem is the ones that come afterwards. Like (2/(1/wacc^2+1/sacc^2)) <- this looks real ugly.

			I guess MediaWiki isn't set up here. But, couldn't those formulas be simplified somewhat?

			<math>hp &=& acc \times \frac{max.health - current.health}{\frac{max.health}{2}}</math>
			<math>hp &=& \frac{2 \times acc \times (max.health - current.health)}{max.health}</math>

			<math>mp &=& acc \times \frac{100 - current.morale}{\frac{100}{2}}</math>
			<math>mp &=& \frac{acc \times (100 - current.morale)}{50}</math>

			Or, even down to non-TeX format:

			hp = acc * (max.health - current.health) / (max.health / 2)
			hp = 2 * acc * (max.health - current.health) / max.health

			mp = acc * (100 - current.morale) / (100 / 2)
			mp = acc * (100 - current.morale) / 50
