I do time's inbetween tweets, take the results, translate the time variations back to the boards. I'll explain and illustrate the best I can. This is gonna be a long one. We'll use the orthodox method, then I'll illustrate another re-read using "keys"?. Here we go!

Looking at 3rd Special Forces, these two. Both of these are Rt's. One done one the 13th at 10:04am. The next one is the same thing, diff time/org. A day before 12th, at 21:29.

So this is what the math looks like. Tools make it easier.
So 12 hours 35m is now drop 1235. Time variations as follows, 1258, 755, 453 (and 1235).

1235. Well just run across at face value. This lets you (the user) discern for themselves. I'll do my own interpertation (extra steps) after these face values.

1258 (23up from our previous) is this.
