GLD correction on Hierarchy level 1
When a correction is applied to Hierarchy level 1 (blue line), its main in fl uence is visible on 25% level. The sum of the adjustment
and the linear transition results in a transition as it is presented by the dash-dotted red line in the graph below.

GLD correction on Level 3
From the graph, you can clearly see the correction that has been done at:
• 1.6% with in fl uence from 0% to 6.3%
• 14,1% with in fl uence from 3.6% to 25%
• 39.1% with in fl uence from 25% to 56.3%
• 76.6% with in fl uence from 56.3% to 100%
GLD correction on Hierarchy levels 1 and 3
Performing corrections on multiple hierarchies result in the sum of the different corrections. From the hierarchy 1 and hierarchy 3
corrections of the example above, the following
fi nal GLD correction is obtained.
