Guild Wars 2

So I was reading on the wiki that fractals below your personal level rewards you with 6400 + 8 * Completed difficulty * (Personal reward level – Completed difficulty) karma. (source: http://wiki.guildwars2.com/wiki/Fractals_of_the_Mists#Personal_Reward_Levels)

I just completed a level 18 fractal w/ a personal level of 19 and only got 900ish karma (could have been in the 700s, i dont remember). Am I missing something?

Am I missing something?

Karma, i guess.

To get the 6.4k it would have had to been 19yours 27level completed if i remember how it works correctly.
