At some point, the cracker is going to reach diminishing returns.
Presumably some fraction of the remaining 15% will be completely random, from people using password managers or similar. These could only be cracked by brute force (assuming they are truly random), and since they're also likely longer, it's unlikely they would be cracked any time soon - they're just not worth the computational investment to the cracker.
