In the hockey stick plot, it graphs the index of k and shows that the best is at 1. However, it says this means k=1 is the best. But at index 1 wouldn't it be k=2?

There may be a little bit of confusion here but k uses zero-based indexing and so k = 1 corresponds to 2-dimensions while, say, k = 2 corresponds to 3-dimensions
