Congratulations to all the recent shinies, and good luck to everyone here!
I am just popping in to give you people an update on what I have been up to lately.
I am still SR'ing on my US version for a shiny Articuno, which I have been doing for a few days now. I do not really care much if Synchronize fails on this one as well, but it would be nice for it to work.
I have been playing through my UM version some also, hoping to get to the postgame and SR a shiny Stakataka (then perhaps another Poipole so I will have both it and Naganadel shiny). My US shiny Naganadel is now level 100 and Hyper Trained flawless.
As of one month into my Pokémon US version, I believe I have successfully SR'ed 16 or so shinies, all UB's and legendaries. I can check on that number once I finish this Articuno hunt to be sure though. I do plan on continuing these hunts, as I have been finding them quite enjoyable. From working my way through Ultra Space to actually encountering whatever legendary I find, it has been a nice change from some other Pokémon hunts I have done in the past.
EDIT: Ok, I just caught that shiny Articuno. I was not expecting it at that moment. I has woken up about half an hour before then, and I was just doing some SR'ing to do something.
It only took a single Ultra Ball on my first try to catch it. I did not even need to have it faint my starting Synchronize Kadabra.
Modest Synchronize worked, and it has an IV spread of 31/x/31/x/x/31. Yay.
I will probably continue this hunting through Ultra Wormholes, along with continuing my playthrough of my UM version.
