I would rewrite this section as such:
> Benchmark/ips will report the number of iterations per second for a given block of code. When analyzing the results, notice the percent of [standard deviation](http://en.wikipedia.org/wiki/Standard_deviation) which tells us how spread out our measurements are from the average. A high standard deviation could indicate the results having too much variability.
> One benefit to using this method is benchmark-ips automatically determines the data points for testing our code, so we can focus on the results instead of guessing iteration counts as we do with the traditional Benchmark library.
