 the remaining 3 `vmstorage` nodes could provide the `-replicationFactor=3` for newly ingested data.
 
 When the replication is enabled, `-replicationFactor=N` and `-dedup.minScrapeInterval=1ms` command-line flag must be passed to `vmselect` nodes.
-The `-replicationFactor=N` improves query performance when up to `N-1` vmstorage nodes respond slowly and/or temporarily unavailable. Sometimes `-replicationFactor` at `vmselect` nodes can result in partial responses. See [this issues](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1207) for details.
-The `-dedup.minScrapeInterval=1ms` de-duplicates replicated data during queries. It is OK if `-dedup.minScrapeInterval` exceeds 1ms

+The `-replicationFactor=N` improves query performance when up to `N-1` vmstorage nodes respond slowly and/or temporarily unavailable, since `vmselect` doesn't wait for responses from up to `N-1` `vmstorage` nodes. Sometimes `-replicationFactor` at `vmselect` nodes can result in partial responses. See [this issues](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1207) for details.
+The `-dedup.minScrapeInterval=1ms` de-duplicates replicated data during queries. If duplicate data is pushed to VictoriaMetrics from identically configured [vmagent](https://docs.victoriametrics.com/vmagent.html) instances or Prometheus instances, then the `-dedup.minScrapeInterval` must be set to bigger values according to [deduplication docs](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#deduplication).
 
 Note that [replication doesn't save from disaster](https://medium.com/@valyala/speeding-up-backups-for-big-time-series-databases-533c1a927883),
 so it is recommended performing regular backups. See [these docs](#backups) for details.
