You’ve expanded on your User Needs very well. But, you’ve lost the traceability. The User Needs are the highest level, let’s call that Level 1. Then each of the User Needs will be decomposed into Level 2 requirements, written at the System level. Then each of the Level 2 requirements will be decomposed into Level 3 requirements written at the Subsystem level. And so forth. And, that trace (or link) between all of these requirements is vital. The Requirements Traceability Matrix (RTM) provides that trace through the Unique Identifiers.
So, it would go something like this,
(Level 1) 1.0 User Need #1
(Level 2) 1.1 System Requirement #1 which comes from the User Need #1
(Level 2) 1.2 System Requirement #2 which also comes from the User Need #1
and so forth, as many Requirements as it takes to fulfill the User Need #1
(Level 1) 2.0 User Need #2
(Level 2) 2.1 System Requirement #x which comes from the User Need #2
and so forth.
