Recently, people keep saying "I saw it on the chain," but honestly what you're seeing is "the chain provided by a certain node/RPC," which may not be the current state of the chain... Nodes are slow to sync, RPCs are rate-limited and queued, indexers re-run parsing and caching, and finally it reaches the data tools/tagging system layer, where the delay becomes even more normal. A few days ago, there were also complaints about some tags lagging behind or even being misleading, which I don't find surprising: they are essentially second-hand processed products, not the blocks themselves.

I personally trust data a bit more, but only if I know where that data comes from and how often it updates; otherwise, intuition might be more reliable—at least you know it's "slow" and "subjective." Anyway, I now compare multiple RPCs/browsers when checking on-chain data, and when I see an "anomaly," I first consider that the pipeline might be clogged, rather than the market suddenly becoming smarter.
