I wonder if the section on leakage should be moved further up.
I also think there should be a mention of leakage at the very start, because it's really important and it may come a bit late (even though it's not that far down the page)

ok I added a (bold font) mention of data leakage at the very start. for the paragraphs that follow I think the chronological order of when you meet problems is roughly this one (building a pipeline at all, making modelling choices, validation) but that is indeed debatable
