the [5] is correct and will explain it for newfags. on April 12th q posted and left the delta [5] for us. using the 2nd graphic of the dates. write down all the dates that have [05] delta. you get

12/12

2/10

4/11

6/10

recheck q posts for these dates and on Feb 10 (2/10) we have a single delta post [5]. deltas match.

posts from past drops will be relevant to whatever q is talking about on future posts.
