In this lesson, it says

1518 times 5 seconds, divided by 60, tells her that her script will take about two hours to run. As a final check, she opens another terminal window, goes into north-pacific-gyre, and uses cat stats-NENE01729B.txt to examine one of the output files. It looks good, so she decides to get some coffee and catch up on her reading.

Where do we get 1518 files? There are 17 files in the dataset.

I'm sure this has come up before (can't find the issue), and someone suggested that the dataset contained a subset of the example in the story. I thought this had been fixed but I guess not. Also episode 2 says there are 1520 files 😄
