Catch probability with multiple throws

In order to help Trainers understand their overall odds when catching Shellos (West Sea), we enable the functionality to showing the total chance to catch it depending on the number of available throws. We calculate this chance as if you repeated the same throw N-number of times.

To activate this functionality, change the number of Number of throws to a value greater than 1. The Number of throws option is available in the configuration options above the chart

Catch rate formula

Pokémon GO catch rate formula can be expressed as follows:

CATCH_MULTIPLIERS = ball * curve * berry * throwType * (type1Medal + type2Medal / 2)
CATCH_RATE = 1 - Math.pow(1 - baseCatchRate / (2 * cpm), CATCH_MULTIPLIERS)

There are different multipliers that come into play when calculating catch rate.

Curved throws are more effective than regular throws, stronger types of Poké Ball have a higher catch rate, and using a Razz Berry or a Golden Razz Berry also improves your chances.
