Password entropy is calculated using the pool size $R$ and password length $L$ used to generate a password:
$$ E = log_2(R^L) $$
where a brute-force attack will need an average of $2^{E-1}$ guesses to crack a password with $E$ bits of entropy.
By default, pkpw chooses 4 Pokémon names from the pool of 913 known
Pokémon, resulting in an entropy of
$$ E = log_2(913^4) \approx 39.338 $$
bits. A brute-force attack that knows to use the 913 known Pokémon names as the pool of values would take $3.474 \times 10^{11}$ guesses on average to correctly guess a password, or a bit more than 11 years at 1000 guesses per second.
At an average length of about 7.5 characters per Pokémon name, passwords generated using the default settings have an average length of about 33 characters (4 Pokémon names, plus one space separating each name for a total of 3 spaces). A brute-force attack that uses a pool of 95 standard US keyboard characters (alphanumeric, special characters, and space) would be working against
$$ E = log_2(95^{33}) \approx 216.805 $$
bits of entropy, taking an average of $9.201 \times 10^{64}$ guesses, or $2.916 \times 10^{54}$ years, to correctly guess a password.
