This new system is what the fan community is calling AVs (Awakening Values). With Pokémon Let’s Go, Pikachu & Let’s Go, Eevee having no 'wild' and randomised combat, the system has changed once again and is now a bit more in-line with the setup seen in the first few games. Pokémon’s stat system has been the same since 2002, with monsters gaining EVs in combat which are then used to determine a power boost which scales based on the Pokémon’s level.
