This application calculates the Base Stat Ratings of a given Pokemon stat spread. Base Stat Ratings (BSR) are used as part of Smogon's Create-a-Pokemon Project, during the Stat Limits and Stat Spread Submission stages. There are 5 different ratings that are calculated:
Physical Sweepieness and Special Sweepieness, which measure the offensive sweeping ability of a Pokemon. Physical Tankiness and Special Tankiness, which measure the bulk of a Pokemon Base Stat Rating, which gives an overall rating to the entire stat spread, based on the previous 4 ratings.
These ratings were developed by former Smogon Administrator X-Act, and the original formulae can be found at http://www.smogon.com/forums/threads/base-stats-ratings-version-2-0.64133/
