He's Konoha's #1 jutsu specialist, and for all we know, he's been perfecting that technique for over a decade. (I'm just making a point, it could have taken a much shorter time).

obviously not long if he teached it to sasuke in like 1 month (in the lil break they had from the 1st round of the chuunin exam to the 2nd round) and like u said, he's konoha's #1 jutsu specialist, and sasuke is not, so if it took sasuke 1 month or so to learn it, then it mustve took kakashi MUUUCH less time.
