To clarify, if I were to do this, is this the right process?
1. Use Time Finder with blank ID fields on Method 5 (standard seed) with IVs I want.
2. Use a seed from time finder (here, 2115D85AE3DE1F1B Frame 15), then input the seed into the main window, choose a nature, frame and encounter slot (here, Adamant, Frame 49, slot 1).
3. Put the seed (2115D85AE3DE1F1B) and frame (49) into Pandora's Box, and then choose from a list of seeds there. (here, 2115D85AE3DE1F1B intial 28, final 31).
4. Hit seed 2115D85AE3DE1F1B and advance 3 frames using the "no" to your name trick.
If I'm correct, this will then allow me to get my IDs, then easily hit seed 2115D85AE3DE1F1B with shiny, IVs and Adamant?
The only thing I'm not sure about is, what are the differences between the PID frame (here, 49), and the seed frame (15)? I would have thought they would have to be the same, but the PID frame starts at 40. I'll have another read over the guide, but that's all I'm missing! :)
