Calculation used

catch-rate

Worked out from Bulbapedia: Stat - Generation III onward formulas and 5 other sources.

This is the Generation III/IV model. Later generations add critical captures and different ball behaviour.

How this is worked out

3 steps

a = (3 x 30 - 2 x 1) / (3 x 30) x 45 x 1 x 1 = 44
b = 1048560 / (16711680 / a)^(1/4) = 43690
Capture probability = (b / 65535)^4 = 19.75%
