It depends how often you want to send those three events. If you want to send them continuously, publishing event 1 again immediately after sending event 3, then you probably will want to wait 1 second between publishes.
If you will wait more than 3 or 4 seconds before publishing again, you can send all three out without waiting between them.
In the more common case of sending a burst of events periodically, say every 30 seconds or few minutes, you do not need to wait between publish 1 and 2, or between 2 and 3.
