"A more realistic "suggested group size" for raids"

#PokemonGO: Did you ever pay attention to the "suggested group size" for raids? 5 for a Magikarp, 9 for a Muk, 13 for a Machamp and 20 for a legendary.Of course it doesn't make sense.Here I propose a (simple?) formula to calculate a much more realistic "suggested group size".The formula is: Suggested Group Size = ceiling [Defense x HP / Time / Vulnerability / 666] (edited).Replace 1000 666 with 2400 (heuristic value) to calculate the minimum group size, although http://ift.tt/2yqcnP0 is much better for this purpose.Defense x HP is just the raid boss's tankiness.Divided by time (176 for Tier 1-4, 296 for Tier 5), it's the needed DPS (Damage Per Second) to defeat the boss.Vulnerability = 1.4 if the boss only has single weaknesses, 1.96 if it has a double weakness.So here is the table for current/past/foreseeable raid bosses:Raid BossBase DEFHPVulnerabilityDifficultyMinimum Group SizeSuggested Group SizeTier 1Magikarp1026001.40.211Quilava1296001.40.311Croconaw1516001.40.411Bayleef1556001.40.411Tier 2Exeggutor15818001.960.812Magmar16918001.41.212Electabuzz17318001.41.312Muk18418001.41.313Weezing22118001.41.613Tier 3Gengar15630001.41.913Machamp16230001.42.013Arcanine16630001.42.014Vaporeon17730001.42.214Alakazam19430001.42.414Jolteon20130001.42.424Flareon20430001.42.524Tier 4Charizard17675001.963.826Rhydon20675001.964.527Tyranitar21275001.964.627Lapras18075001.45.539Snorlax19075001.45.839Venusaur19875001.46.0310Blastoise21075001.46.4310Tier 5Moltres184125001.964.026Celebi210125001.964.527Articuno249125001.965.439Entei180125001.45.439Mewtwo182125001.45.539Zapdos188125001.45.739Raikou210125001.46.3310Mew210125001.46.3310Ho-Oh301125001.966.5310Suicune235125001.47.1311Lugia323125001.49.7514EDIT: I multiplied all estimates by 1.5 (before rounding) in order to make these estimates very conservative, i.e. suitable for an average trainer level of 13 instead of 30. Still, all level 1s are soloable and all level 2s can be done by 2-3 players. Definitely no 5 players are needed for a Magikarp.I assume raids have to be a challenge and not an easy 30-second job. I did 19 Entei raids with different raiding groups and we never failed if at least 5 people were there.EDIT2: Minor Text Fixes™.EDIT3: More Minor Text Fixes™. via /r/TheSilphRoad http://ift.tt/2ggMzul
