Here is what I'm reading on msdn ms152560 (referenced in today's question)

...and these are excerpts...

In reference to the 'sync with backup' option...

Setting this option on the distribution database has no effect on replication latency.

Then a couple sentences down...

It is recommended to set this option on the publication database if your application can tolerate additional latency.

So it seems to me that setting 'sync with backup' option can increase latency when set on the publication database, but there is no effect by setting it on the distribution database.

That answer would be 'neither of these' from today's choices.

What am I missing here? Help me, HELP ME, help me!!!
