The whole system of block builders and bundles—retail investors really don't need to push themselves to become half-engineers. To put it simply, all you need to know is: the transaction you click may not be "queued in order," but instead is being bundled, jumped ahead, or inserted, and as a result, the price you see / slippage gets distorted. Don't immediately blame yourself on the chain for being slow; often, it's just how the rules are written.

My personal passing line is: don't force large swaps, prefer to split them into batches; don't set slippage too wildly; use routing with some anti-front-running features if possible; when encountering strange trades, first suspect the bundling method, don't immediately assume the project team is running away. Recently, everyone's focus on staking unlocks and unlock calendars causing sell-off anxiety also seems similar; reading too many announcements can lead to overthinking, but when it comes to dumping, it’s still about how your transaction was bundled. Anyway, I just consider myself queuing in a not-so-fair line, and all I can do is avoid standing in the easiest spot to be stepped on.
