4: Slight effect or effect not determinable

Rate the Estimated Technical Difficulty of the Activity
I: No Difficulty - Proven concepts and techniques exist or quick agreement anticipated

2. Scope:
a: Define the areas to be covered or addressed by this activity or document:
Exchange yl,n(x) by yu,n(x) and vice versa in 14.3.5.3 and 14.3.5.4
- include D in report section of PV42


b: Expected result of activity
