Maybe the Jedi can learn that with ease when he or she is still at the tender age. they would then have the ability to grow up with it and master it as the midi-chlorians grow up and develop with the mind of tha Jedi.
Luke had to learn it all as an adult therfore it would have been much harder in chronological terms. i just feel that would be the right thing to say at this point. at least thats my theory.
