          About our ranking methodology

          Our guide provides detailed information on recommended Pokémon and moves that are most effective against Mega Slowbro in Raid Battles. Whether you're looking for the best counters to take Mega Slowbro down quickly with high DPS, or the tankiest counters that can withstand its attacks, our guide has something for every trainer.

          When calculating the best counters for any Pokémon, our simulator takes into account various factors, such as the defender's typing and average DPS against each attacker, the weather's influence, energy left over from using charge attacks, Shadow Pokémon attack and defense stat changes, and more. During the initial phase of simulations, we calculate DPS and TDO for each attacker that is currently available in the game, and then we continue to rank them.

          We use a ranking method developed by a Reddit user named /u/Elastic_Space, which is described in detail in this Reddit post. It is a fairly complicated, but very well thought-out mathematical model for predicting simulation results without actually running the simulations. It also correlates with field data almost too well not to be used. Reddit

          Our Time to Win (TTW) and Faint numbers are also estimated, and should be taken with a grain of salt. Since we do not account for factors like Friendship and Mega damage boost, they will differ from actual experience in the field.
