Elementor sites show pre-optimization median mobile LCP of 3.8–5.2s — well above Google's 2.5s threshold

Claim: corewebvitals.io reports Elementor sites typically show median mobile LCP of 3.8-5.2 seconds pre-optimization. Post-optimization typically lands at 2.0-2.8s — still requiring "ongoing maintenance as plugin and builder updates frequently reintroduce bloat."

Confidence: Industry-consensus.

Implication: The Elementor performance penalty is not a one-time fix. It's a maintenance posture — every plugin update, every theme update, every new widget can regress LCP back over the 2.5s threshold. This is the architectural argument against page builders for sites that need stable CWV.
