Why this is mistaken
Accumulating errors can make iron curtain larger; reversing errors can make the current rollover effect larger. Compute both from one signed schedule. The purpose is complete visibility, not finding a uniformly conservative shortcut.
Where to watch
When this mistake may appear
- An error originates and reverses over multiple periods.
Check your work
Your work may contain this mistake if:
- Chooses one method without computing signed origin, reversal, and ending layers.
