I did that too, with delays 485-499 and 25/0/25/0/25/31, finding many results (about 150 KB worth,) but my problem is that I can't find out the Method K frames. I don't want to reach frames above 100000 or something in SS (ideally, I want something under 3000, but I'd go higher if I needed to.) The way I found Method K frames was by plugging random ones into RNG Reporter, but that is definitely not practical when I have so many results.I did a search with pokeRNGDP:
"Search for: Shiny (TID: 23842 SID: 21070) 20/20/20/20/20/20
Found 1448 result(s)! "
I obviously won't post them here. I asked for IVs greater than or equal to 20, no fixed nature, no special hidden power, delays between 493 and 3000 that will work for any year if you are using pika-timer.
