>>26792911Here's what I think happens:
>Pokemon to be spawned is taken from the frame the encounter is generated>Synchronize moves this pokemon to the appropriate frame and can turn it shinyOn Route 103, I got Wurmple/Zigzagoon/Poochyena with 1 frame. I should mention i have a GIGANTIC amount of frames for this shiny frame, 45. Meaning 45 chances to get a different encounter.
Obviously this won't work well if you have say, 5 frames or so. You should try playing with Battle Videos to advance time, since i finally got it down. If you want me to explain it, i can in another post.
