The coordinates of Spinda's spots are dependent on the PID, so you can directly determine the PID of any Spinda - there's a calculator somewhere.
But if we were to conduct any more egg PID research on Emerald, I'd rather use mingot's RSEdecode program with an emulator, it's much faster and reads the PID\IVs directly.
