The Min/Max values are calculated for a Pokémon at level 100. Maximum values are based on a beneficial nature, 252 EVs, 31 IVs. Minimum values are based on a hindering nature, 0 EVs, 0 IVs.
Tiers are calculated from the Pokémon with the highest available stat for that stat. Example: Blissey has the highest base HP at 255, so all tiers are divided by 6 from 255. Whereas the highest DEF is calculated from Shuckle at 230. This shows a better representation of where a Pokémon's base stat lies compared to the highest that stat can be. The length of the stat relative to the Tier also shows where it sits inside the Tier.
