Lately, I've been bombarded with a bunch of terms like "data availability / ordering / finality." To put it simply, I see one main thread: whether the "results" you see are reliable and whether they can be altered. Data availability is like whether the original ledger records are publicly accessible; ordering is about who writes first and who writes later, and whether anyone can cut in line; finality means that once you flip past this page of the ledger, it won't be torn back or changed.

No wonder on-chain data tools and various tagging systems are being criticized for lagging behind or even misleading people... If you stare at the dashboard for a long time, but the underlying transaction order changes, or some layer of data isn't released at all, it's easy to get misled. Anyway, when I look at profit routes now, I first ask myself: which step in this chain or scheme is most vulnerable to "tampering," and then decide whether to trust that fancy chart.
