Thanks! This is significantly faster (and also easier to read in my opinion) when ran on a real dataset:

Execution Time (Original): 293 seconds

Execution Time (New): 53 seconds

5.52x speed improvement.

Would you be able to explain why this approach is much faster (or how the old one was so slow)?
