Not 100% as I haven't tested it myself, but I was talking to user
<Totes> earlier and apparently it is possible to use Synchs.
Thanks for the info. I managed to get it to work, although there was one time when I got the non-synchronized version of the target for whatever reason.
I'm curious about random encounters like Ultra Beasts now. Does anyone who's managed to successfully abuse the RNG for a UB know what kind of frame deviation there is from stationary encounters, or if there is a definite frame deviation? I've read Blastoise's guide and whenever I've tried to capture a Celesteela in Haina Desert, in an area with no NPCs or dust clouds, I've still not landed anywhere near my target frame. Is it more complicated than just subtracting a certain number of frames to account for the 3.2 seconds of Honey use?
EDIT: I realize that may not have been completely clear. What I'm wondering is if I can literally just subtract 96 (or 56 or 63) frames and still use the stationary RNG calc, provided I'm not in an area with a lot of interfering factors?
EDIT: Okay, I am 100% certain now that it's possible to hit a synchronizable frame with a Synchronize Pokemon in lead and the target Pokemon still will not be synchronized. I have had this happen 3 times now. I have absolutely no idea why some frames that are marked to work with Synchronize actually do not synchronize.

EDIT: Also, it is evidently possible for checking the "Consider blinking process (sync)" box to interfere with Synchronize usage in some cases.
In seed B83545F2, I was aiming for frame 1030 with the aforementioned box checked. My target was Tapu Fini, with 1 NPC.
When I searched by stats, the Tapu Fini I caught appeared to not exist in that seed. Then I unchecked "Consider blinking process (sync)" and saw that I
had hit 1030, only
without the blinking box checked. Yet I was using a Bold Synchronize Pokemon.
Basically, it seems that, in this case at least, the process of advancing to the target frame was just like it would have been without a Synchronize Pokemon.
Can anyone offer some insight into this? Because my thinking for the past week has been "Need to synchronize natures? Check the blinking box."
