I meant 'show inheritance' for your previous beedrill example, since that's what we're looking at.
Tho from this example, it looks like Pokefinder is more accurate than RNGReporter, since you're getting the exact values.
So you can continue to progress with Pokefinder, it looks like RNGreporter is just getting the numbers wrong.
Probably another reason (or maybe a consequence of) why it is a dropped project..
Regarding the method: https://github.com/zaksabeast/PokemonRNGGuides/blob/main/guides/FireRed and LeafGreen/Egg RNG.md
It doesn't mention anything about the method, but it's using a normal one in the screenshot.
