When you do the devidian missions watch the idle chat of the ferengi bar boss. He offers 4.7% discounts on drinks.
I just spotted another one... Traelus satellites daily opening prompt:
Captain, the satellites in this system are part of an advanced warning network that signals if enemy ships are approaching Federation space through this sector.
Starfleet lost contact with the network 47 hours ago. It could be an equipment malfunction, but it could also be sabotage. Both the Klingons and the True Way could take advantage of holes in our sensor nets to attack the Federation.
Edit: And another one in the Alhena refuelling station daily:
Administrator Borka: The Alhena Refueling Station has an exclusive contract to supply ships on the front with deuterium.
As per the contract we signed with your government, it is your obligation to protect us.
It's all spelled out in Section C, Subsection 12, Addendum 2.5-A, Paragraph 12, Revision note 4.7. Have someone in your government check the contract, if you don't believe me!
i dont think ill do stuff like 47, but i do plan to dot little references to things that have happened in star trek over the years. some might be obvious and some less so to try and expand the universe somehow.
The latest one I found was from the Tutorial, complete with voiceover from Zachary Quinto:
