well free pulls contribute towards getting your rares, so in some sense most of those 360 free pulls have already been counted in the 14 rares you have. You should really think of it as 14x60=840 pulls for the rare (going for a 60 on avg, but that's actually low balling it), and then somewhere up to your 15th rare, so as high as not quite 900. So you are in fact close, just not as close as you think. Counting rares seems to be the most reliable, but its still not guaranteed. For both my supers (gnw and kage) as well most of my group mates who I asked and could remember pulled their super between the 17th and 18th rare, but that could just be coincidence since thats near the 1k mark everyone quotes.
