I counted my public talk time. I counted 1 hour when I gave 45' talk, and 1/2 hour when I gave a 30' talk (after the recent change). That includes memorial talks.
I did not count any other kind of talk.
Of course, when I went for a talk to a distant congregation, I used to take along with me at least 1 unbaptized publisher, so the actual counting was a lot more than 1 hour.
