Full potential Anakin is Father-level and can slap Yoda and Sidious into a coma at the same time, but even The Force isn't omnipotent, nevermind one person who uses it.
The only person who has a chance of achieving that is full potential Anakin with all of Palpatine's resources at his disposal, and even then I still have no clue how he would go about it. Plus if he became truly in tune with the force he wouldn't care enough to pursue it I imagine.
But it's a fun thought nonetheless.
in terms of real world IQ and jedi?
one way to asses real world IQ without actual IQ testing is
is the person able to pick up languages
is the person able to pick up scientific concepts
is the person show aptitude in academic subjects, as IQ was designed for academic intelligence
on this criteria
Rey hands down is the second smartest Jedi, after anakin
Yoda showed zero technical aptitude and no multilingual aptitude
Rey shows she is poly lingual and she is familiar with technology
Rey is self-taught
a real world rey would be someone who speaks 5-10 languages by age 18 and is intimately familiar with computer, iphone software electrical engineering concepts
can fix a broken computer and high level software engineering
