XF 1.5 Google search results - structured data - posts and authors for a thread

[Mouth]

Anyone know the reasoning why Google search results show structured data for how many posts and authors a thread has for some thread, but not others? Is it something very new that's only just come in?

I see no special markup that would explain this. It's probably just Google figuring out this interpretation on their own.
