Physics View of Catch Probability
A Pokémon GO catch is not a physical collision, yet it can be studied like an event model. Each throw is an attempt. The ball, berry, curve, medal, and circle accuracy change the strength of that attempt. The calculator converts those choices into one combined modifier.
Why Modifiers Matter
Small bonuses can become powerful when they multiply together. An excellent curve with a strong berry can greatly improve a hard raid catch. This is why planning matters. Players often remember the ball type, but they forget medal bonuses and throw quality. Both can shift the final chance.
Base Rate and Level
The base capture rate measures species difficulty. A common wild Pokémon may have a high rate. A legendary raid boss often has a low rate. The CP multiplier represents encounter level. Higher values usually make the catch harder. Weather boosted encounters can therefore feel more difficult, even with the same species.
Single Throw and Many Throws
The first result shows the chance for one successful contact. The cumulative result shows the chance after several throws. This is useful for raids, research rewards, and wild encounters. Ten low odds throws can still create a fair combined chance. One very strong throw can also beat many weak throws.
Using Exact Ring Ratio
The exact ring setting is for advanced users. A smaller target ring creates a stronger throw bonus. Enter zero for a perfect tiny ring. Enter one for a full size ring. Most users can choose Nice, Great, or Excellent instead.
Exporting Results
The CSV file is useful for spreadsheets. The PDF file is useful for sharing a short report. You can compare different balls, berries, medals, and curves. Try changing one setting at a time. This makes the final effect easier to understand. The calculator is a planning aid, not a guarantee.
