Since is it above 225, the Pikachu will be caught.

Understand the Pokémon Platinum catch rate calculation, including how HP and specific formulas determine if a Pokémon is caught.

The catch rate calculation in Pokémon Platinum involves a specific formula. For example, if a Pikachu is at full health, the calculation proceeds as follows:

(3 x 28 - 2 x 28) x 190 x 1 / 3 x 28 x 1 = Final solution

First, (3 x 28 - 2 x 28) equals 28.

Next, (28) x 190 x 1 equals 5320.

Then, 5320 / 3 x 28 results in approximately 63.3 (with 3 repeating).

If this final value is below 255, the game then uses a random equation to determine the outcome.
