I'm very happy to see you buddy. I had a big idea last night that made me recall these.
I'm about to post something very relevant to your work, working on the graphic to explain it now.
I'm finding more than just the deltas are important. Some of my markers probably won't have nice neat slice of time, due to them being hours apart.
You could always just ignore the hours, and see if the minutes give you a nice delta to fill in.
At minimum it would be helpful to just plot the timestamps on clocks for the ones on my markers list that aren't the Q/POTUS type of [marker] (where they post/tweet close together)
I'm working on something BIG related to the map (maybe), but it is taking a while to put together a graphic that can explain it. Trying to rush and get something workable done while there is some actual interest in the MAP going in the bread.
