More Info
Last month we made some tuning adjustments to the TTI algorithm in our JavaScript tag for real user data, designed to more closely align with Google Lighthouse. This same update will be deployed with Synthetic Agent v5.3.0. This will have very little impact on TTI times for most sites, but some may experience a one-time fluctuation in TTI based on page structure.
