Percent Solver Calculations

The Mathematics behind the Percent Solver routine

For determining the closest fit between multiple target values and actually calculated data, the value of the following formula is minimized: diff = Sum[(actual%value_i - target%value_i)²], which in words is the summation of the square of the ith calculated percentage value minus the ith target value. The minimum value of this formula should be obtained when all actual values are closest to their target values.
