Sorry for the very long delay. I do have some examples now. Sometimes the query is right, sometimes the count displayed in the thread is right. Sometimes they report the same number and are both right!
I noticed that when the counts differ, the threads have had posts split off to new threads.
Examples: Query results correct, thread count wrong
Kudo & Win shows 17 participants in the query results, but when I unfold the info in the thread, I see 21 “users”. Actual count: 17.
No connection to cellular network… has 26 participants in the query results. The thread shows 24. Actual count: 26.
Moto X4 Coming Soon to Republic Wireless! returns 21 participants in the query results, thread indicates 22, actual count: 21.
Examples: Thread count correct, query results wrong
Google Pixel2 and Pixel2 XL BYOP Support has 21 participants in the query results. The thread claims 19. Actual count: 19.
System Update for Moto X Pure (GSM Only) query results return 11 participants, thread count indicates 10. actual count: 10.
