I think one post for practice (all of them combined), and one for quali and the race each would be good. Something I'd like this community to avoid that's common on the subreddit is multiple posts for the same thing with virtually the same discussions.
For example there's a post with the top 3 in quali/race, then there's a post with the full classification order. These posts could be considered the same.
Along the same vein, it might be a good idea to avoid posts that could be comments in another threads. For example posts outlining who's out in Q1 or Q2 could just be stickied comments in quali threads, and given there's no limit to how many comments can be on a comments, discussion can remain just as detailed without crowding the feed.
