Synthetic interaction sub-parts or the framework

Does the framework explain the synthetic interaction sub-parts difference?

On React, 100% of sites with under 35ms lab interaction duration synthetic interaction sub-parts have a good INP, against 100% of React sites with 35 to 65ms lab interaction duration. Within React, sites with under 35ms lab interaction duration and 35 to 65ms lab interaction duration have a good INP about equally often.

How input delay, processing, and presentation add up

Every user tap or click waits for background main-thread tasks to finish (input delay), runs event callbacks (processing), and recalculates styles and paints the next frame (presentation). Across 1,687 sites (50.4%) under 35ms in lab interactions, 100% pass field INP at an 38ms median, versus 100% (45ms median) on the 6.8% (229) exceeding 110ms.

Understanding synthetic interaction sub-parts

Keep event handler processing lean and yield before forcing layout or paint updates so total interaction latency stays well below the 200ms INP threshold. Across all audited sites, 50.4% finish under 35ms (100% good INP, 38ms median) versus 6.8% above 110ms (100% good INP, 45ms median).
