On the topic lists, replies is always one less than posts - that doesn’t apply to the read time estimation text, though.
It seems to me that it should either say “posts” or use the reply count instead of the post count.

Let’s get that changed to say “posts”, then. Simple copy change, PR?
nahh we should clean it for consistency with front page, use replies correctly there throughout.
Ok I vote you can do that one! Should be easy…
