post_event_list is the result after VISTA rules and processing rules are
applied. If you have neither in your implementation, they should always
be identical.The lookup file event.tsv contains all values, including
custom events 100+. For a data feed that I have on my test site, event
101 is "20100" in my data feed files. It might be different on your
site, depending on your analytics contract and when the report suite was
created.
