I really liked the "solve-yourself" lab questions! However, I have something I can't get my head around. When experimenting with the lab questions, I came to the following conclusion: - UNNEST didn't seem to affect the queries at all. Compare the following queries: `SELECT p.name, split_time FROM racing.race_results r, r.participants p, p.splits split_time WHERE split_time = 23.2` with the suggested lab question solution. There doesn't seem to be a difference? - Furthermore, if I didn't add an alias to p.splits, the query didn't work no matter how much I unnested. It would be great if you could look into these things, because other than that, this is a great lab!
