How to interpret the result
The three values illustrate variation. They are not real performance statistics for a site.
Deciding what to do next
Separate error or different-body responses from normal-page comparisons. Do not report only the minimum as improvement.
Feature scope
Measure the received body and elapsed fetch time from the Korean server, not all assets, rendering, pure TTFB or a Core Web Vitals score.
