Started more threads than the number of posts you made?

I was just looking at the data for cheesedonkey (because of a bumped thread) and he made 225 posts, but started 265 threads? So my question is: Huh?

How—board statistically—does someone make fewer posts than their number of threads?

265 threads started, 225 replies to existing threads.

Discourse doesn’t count threads started as “posts” on your profile.
