Think of [5] as 5 minutes apart. Q and Trump would tweet/post 5 minutes apart. Think of [10] as 10 minutes apart. Same scenario. This has been used several times as a way to confirm things.  So this anon said [0] as in zero min apart. That would mean Q and Trump would have to post/tweet at the exact same time. That’s what happened! They will give little Q proofs like that sometimes when asked.
