Most live pages use JavaScript polling or auto-refresh to check for new results every few seconds. This makes the displayed numbers update quickly when the source entry appears.
Cache and propagation delays can cause a short period where a new result is visible on some systems sooner than others. After the backend confirms the number, charts update consistently.
High traffic around result times can momentarily slow updates. Well-optimized systems handle this through caching rules and lightweight JSON endpoints.
Why did the number change twice?
It could be a propagation or cache refresh issue; the confirmed result appears shortly.
How often do sites poll for updates?
Commonly between 5–20 seconds depending on implementation.
Can traffic affect updates?
Yes — peak traffic can cause delayed display or partial updates.
