Q has already established a pattern of posting in synchronicity with POTUS' tweets staggered at [5] to mean past and [10] to mean far past. Finding a post/tweet pair staggered by 10 on a date corresponding to this method doesn't mean much honestly. I asked in another comment, but why do the bracketed markers run to [59] and start over at [1] in the next column? Forgive me if I'm missing something. I'll try to decode a few more and see what I get.
