Catch rate/Capture method (Generation V)/Modified catch rate

Generation V follows the formula in Generation III-IV, with all divisions above rounded down to the nearest multiple of 1/4096. However, there are three alterations: If the modified catch rate is greater than 255, the Pokémon is guaranteed to be caught (but a critical capture check will be performed anyway).
 * bonusstatus is now 2.5 for sleep and freeze (instead of 2).
 *  factor: if a Capture Power is active, the catch rate is multiplied by a factor and rounded down to the nearest multiple of 1/4096.
 * Capture Power ↑: ×1.1
 * Capture Power ↑↑: ×1.2
 * Capture Power ↑↑↑, S, or MAX: ×1.3
 *  factor: This factor is multiplied into the HP factor (3 × HPmax - 2 × HPcurrent above) and then rounded to the nearest multiple of 1/4096. This factor is applied if the battle occurs in dark grass, and depends on the number of Pokémon that have been caught in the Pokédex, as shown in the table below, usually making it harder to catch a Pokémon.
