Just one caveat. How long it takes to crack also depends on how the attacker chooses the alphabet range. If you start by assuming a rememberable passwords, the method doesn’t rely on 100% brute force (real attacks rarely are).

You won’t randomly try character, but regular alphabet characters to begin with, but furthermore — you will use concatenation of valid words.

Yes, weird character passwords are a liability because remembering them has people default to writing them down in accessible places, but real word combinations are vulnerable too.
