It should be easy to find, which is why I believe, usually all the way down. Otherwise , after lifting engine for trailer or shallow water, you and other owners would have difficulty finding a repeatable proper position. Recreational boats are not planned for that--should be easy and repeatable.
What did the dealer say? Owner's manual?

In my decades of boating I've never driven a boat that didnt perform better with a modest amount of trim up on the drive, it always helps get the hull out of the water and you feel the steering response change significantly.

This is the first time all the way down is the near perfect setting.

That said, I have never owned or driven a Bravo 3 before,,,

Called factory tech line and they said trim all the way down, then tap trim up maybe 2 times. Seems odd to drag so much hull in the water, but it sounds like thats how these boats are built.
