Ugh I tried to do the same thing, SR for a shiny Rowlet, but it didn't work out as well for me as it did for you. So I preordered the game on Amazon and got the game like 5 days after it came out, but in those 5 days, I had seen people post their shiny starters online, so for some reason, I decided that it wouldn't be that hard (I had never tried to do this before).
I did this for over FOUR MONTHS. My friends would constantly ask me if I had gotten it yet, but after a while, they had already beaten the Elite Four, and I was STILL trying to get that shiny Rowlet.
I ended up being super busy with school, so I stopped trying to SR and just didn't play the game until June, when I finally decided to just start the game without trying to get a shiny.
Anyways, I'm definitely NOT going through that again this time around.
