Its not a definitely Rare pull every 60. Its a rare pull every 40-80, with 60 being the average. (I know of people who get him at 80, and personally, I got him at my 1st 40).
But you should be getting that Sage Naruto within the next 20 pulls I'm guessing. You've already gone to 200, might as well just fini* up and get him. Its like you already ran 40km of the marathon, you're just left with 2km, don't quit now...
