You have set up alerts on a document library to be notified for all changes. User 1 deletes Doc 1 and immediately restores it from the Site's recycle bin.
In this scenario, you receive only one notification that the item Doc 1 was deleted.
If there are multiple events for an item changed by a single user in a alerts timer job quantum, which is 5 minutes by default, then the alert engine will pick up the FIRST event for notification.
To change the alert interval, you would run an stsadm command similar to the following example where the interval is set to 1 minute:
stsadm -o setproperty -pn job-immediate-alerts -pv "every 1 minutes between 0 and 59" -url http://<SiteURL>
