I would phrase this a bit more nuanced as: strong enough to not be
cracked by a skilled attacker <if you believe yourself to be skilled>
with access to <insert your hardware resources/ monetary cost to run on
a rented system here> in <insert the time you took for this here>

I would like to have a large list of wpa passwords that are actually
used in the wild, generate a  statistics file with these and run your
cracker for let's say a week. If someone has these, I'm intrested :)
(Most list I found are just normal wordlists with passwords < 8 and > 63
removed from them, not actually wpa keys that people (or tools) come up
with.
