Well to be clear, I didn't say it was superior, I said it was superior if you could make a particular assumption. That assumption isn't really at all true over something like 10 years.
Why in theory is it better? It's just more sample size factored in together. Using separate years you're essentially adding in the noise from each year all together, which isn't good.
To try to read mystic's mind ahead of time: He's not a believer in multi-year data sets like this for the reasons I've given above - but they bother him more than they bother me. So while I'm essentially saying I like the separate approach here bet than the compound approach with some caveats, I'd imagine he'd state the same opinion in a more resounding fashion while adding in some additional insights along the way.
