Well, even with your precisions, my picture would still represents Ne.
Simply erase the "We have to use Ti/Fi in order to navigate in it" sentence and change it to :
• Ne-dom will simply navigate randomly in the spectrum (prefer the world of infinite possibilities)
From S : He'll get 1-2-3-4-5-6 (and more) possibilities, and will wander randomly to 1a 1b 1c/2a2b2c/3a3b3c/.../6a6b6c etc (and more) possibilities.
• While Ti-dom/Ne aux will prefer prior selection in order to prevent overflowing-informations/ideas (prefer the world of relevant possibilities).
From S : He'll get 1-2-3-4-5-6 possibilities (and more). He'll decide which path is more relevant, and will decide to develop chosen paths (only 2a-b-c, 3a-b-c for example) except if Ti think he missed some information in other paths.
Would that fit ?
