The <event id> is an arbitrary value. The only requirement is that it
is unique within the given service.

The <table id> is simply the id of the table in which the event was
found. Tables 0x4e and 0x4F are for present/following events, and
0x50..0x6F are for events in the future (the higher the table id, the
further in th future).

If you send your "known to be good" data with table id 0x00, it should
overwrite any existing events, provided either the event id is the same,
or they start at the same time.
