According to the official documentation, the target is 1600KB: https://developers.google.com/web/tools/lighthouse/audits/network-payloads
However, even when the payload is larger than the target, it sometimes still shows as a passed audit: payload of 2405KB still passes
What are the other conditions that allow large payloads to pass the audit?
Lighthouse scores are 0–100 based on some log normal distribution math.
1600KB is not a passing score, it is approximately a maximum possible 100 score.
As of right now the values used for distribution calculation are 2500KB point of diminishing returns and 4000KB median, which would correspond to scores of about 93 and 50 respectively.
That puts 2405KB result at ~94 score which is sufficient to pass.
