For wonder Cards do I add two frame to the Spread below or only when i use the RNGreporter?
Selecting a Spread
Eventually, there will be a comprehensive list of all low frame usable spreads, but for the time being if you need something that is not covered below you can use the "Capture Time Finder" in RNG Reporter. Search using the directions from the "Capturing Perfect Pokémon" using method 1 and then add two to the frame number. When searching for an IV spread, the nature attached is completely irrelevant as the PID and IVs are not coupled for Wondercard Pokémon as they are for method 1.
Here are a number of useful spreads that have already been researched:
690302C3, Frame 43: 31/13/31/31/31/31 (Special)
Okay, if I understand what you're saying, you're asking if you should add 2 frames to that, to make it Frame 45. Why would you do that? That's not even close to correct. You're at frame 1 (or higher depending on runners). Do your subtracting and divide by 2 to get journal flips. Rephrase your question if I didn't answer it properly.
