 ## How does this compare to other tools?
 
 To test the performance of of other tools, I created several stego files with different passwords, taken from `rockyou.txt`. I ran each of the tools with their default settings, except Stegbrute where I increased threading for a fair comparison.

-To compare the speed of Stegseek, let's look at the speed for the `1 000 000th` entries (below this value, initialization still takes too much time to get a measurement). At this scale `Stegseek` is `400+` times faster than stegcracker and `250+` times faster than Stegbrute.
-
+To compare the speed of each tool, let's look at the last row of the table (otherwise Stegseek finishes before all threads have started).  
+At this scale Stegseek is almost **4000** times faster than Stegcracker and over **2000** times faster than Stegbrute.
