else

// Scale single component distribution to cumulative sizing
// scaled to fraction basis: ie. 1 passes top-size
CombCPPSizing[ nSize - 1 ] = 0;
for( i = nSize - 2; i >=0; i-- )
CombCPPSizing[ i ] = CombCPPSizing[i + 1] + ( CombRetSizing[i + 1] * ScaleFactor );
// Construct cubic spline passing through cumulative curve
FeedSpline.SetSpline( Sizes, CombCPPSizing );
// Use cubic spline to get fraction passing half apperture size

// Calculate area factors for this screen
A = CalculateA( S );

// Calculate denominator of load equation - ensure not zero
Denom = A * B * C * D * E * F * H * J * K * L * AF * X;
if (fabs(Denom)<1e-8)
Denom = 1e-8;
// Calculate load
V = ( 90 * QF * U ) / ( Denom );
// Calculate efficiency that matches this load
T = CalculateT( V );
// Calculate factor G
