I was able to succesfully get my RNG abused Ho-oh, but one thing bugs me.
1)Before RNG abuse, I saved right in front of the ladder to the rooftop.
2)Then, I reset my game, walked up the ladder all the way to Ho-oh, caught him.
3)I deduced that he was on frame 1 after several rounds for confirmation. (128 step counter was not triggered, and this was after walking up the ladder to the rooftop and all the way to Ho-oh)
4)Then I changed my date to match my target spread's.
5)When I hit my delay, and advanced my frames accordingly, I noticed I was off by one frame, even though I did nothing new except advance my frames.
6)I know I didn't miscount, b/c I did a practice trial run and he was mysteriously on frame 2.
Can anyone explain the reason behind why the frame would change? If it was because it's a step in an area with wild pokemon, why was the caught Ho-oh's frame initially 1 during the previous trial runs? And does walking up the ladder count as a step in an area with wild pokemon? This didn't happen to me when I RNG abused for Lugia outside his cave's entrance.
One last note: in the trials I did, I did not have a syncer at the front of my party. But when I went to abuse for Ho-oh, the spread required me to have a syncer, so I had a dead syncer at the front of my party. Does having a synchronizer at the front of your party advance the frame by one, or any amount?
