Just did my first shiny hunt. Here are a couple of things I found out (might be common knowledge already):
1. Sparkling sandwich + outbreak with Pokemon of the correct type is probably the fastest way to find a shiny.
2. You can't start the outbreak if the Pokemon does not spawn at that time of day.
3. Length of the outbreak depends on the amount of Pokemon defeated and is not time-dependent.
4. You can leave the location of an outbreak and come back later and there will be no increase or decrease in the number of spawns until the Pokemon disperse.
5. Outbreaks are not immediately replaced on the map after you disperse them. (There were 6 total outbreaks on my map and completing four did not make any more appear).
6. You can leave an outbreak and complete a separate outbreak and come back and continue the first one.
Shiny chances:
I used the Sparkling power recipe: Ghost, which provided sparkling power and title power. I completed 3 ghost type outbreaks (Drifloon, Sinistea, and Haunter) and got one shiny (Sinistea). I've completed 5 outbreaks without the aid of sandwiches and got zero shinies.
