Interesting. I tend to view Presence missions more along the classic Royal Navy lines, an complement to the Show the Flag mission -- being seen patrolling near rivals; port visits to allies and friendly nations; participating in exercises with their navies, and otherwise being seen as continuing to show and interesting in keeping an eye on your friends and potential enemies. (With said port visits including throwing tours or parties on the ships, often in support of your diplomats)
Show the Flag is the rarer visits by your big units, often in conjunction with a major diplomatic event; while Presence is the day to day, well, being present.
Friends are reassured that you still care and are paying attention. Potential friends feel confidence that you'll be in position to help them. And potential enemies see that you still have interest in the area and likely aren't going to sit still should they decide to try to expand at the expensise of your friends, or even your remote territories *cough* Falklands *cough*. (Where its said that the UK's decision to withdraw it only ship assigned to the south Atlantic, HMS Endurance, was one of the things that helped the Argentine military rulers that the UK wouldn't actually dispute the lost of the islands)
(All this is why submarines are nearly worthless at presence missions. They can be great for surveillance or intel gathering, and having them near to hand should a potential enemy pick a fight is right helpful. But the very stealth that makes them so good at those missions means they do a poor job at maintaining relationships by being seen to be around)
Now these presence missions normally aren't carried out day to day by your most powerful ships. It's enough that there's a steady stream of smaller ships -- and that your potential enemies know that even though they could defeat one of those, that all that would do is summon the wrath of the rest of your navy down upon their head.
What you're calling presence I'd call more like covert surveillance.
From a USN ~1900 point of view, Shanghai based gunboats were the "Presence" mission ships, the Great White Fleet was a "Show the Flag" mission.
