She couldn't possibly have "GOT ON" her regular bus at 1:15, because (per CD630) there was no bus at 1:15. It was 1:12.

I think she normally attempted to be at her bus stop at 1:15 (to catch the 1:22 bus, because she sure as heck didn't catch the 1:12 every day, unless it was always late), but on Nov. 22 she was just a tiny bit behind schedule.
The FBI report tells you the busses were scheduled to arrive at 1:12 and 1:22, not that they always arrived exactly on time.
It has been my experience, as a young man taking a bus to school every day, that busses in urban areas seldom actually arrived on time.
But - and I have already said this earlier - it doesn't make a damned bit of difference on which of the two busses she actually got. In her mind she needed to be at the bus stop at 1:15, which means that she wouldn't be at 10th and Patton at 1:14:30.
You think it takes three full minutes to walk the one short block from 10th & Patton to Patton & Jefferson?
No, I don't think that. I knew it was less, but I was being kind to you, as the 3 minutes give Callaway a bit more time between the shots and his arrival at the crime scene. Less than three minutes would mean that Markham arrived at 10th/Patton even earlier than 1:10.
This may go over your head, but the totality of the evidence involves three people; Markham, Bowley and Callaway.
Markham arrived just prior to the shots and Bowley a minute or so after the shots. Callaway was further down Patton, when he heard the shots and saw a man with a revolver running towards him. After the man turned on to Jefferson, Callaway ran to the Tippit scene. As both men were running, it couldn't have taken Callaway much more than about 2 minutes to get to the scene, and by that time Bowley had already arrived and made his 48 seconds long radio call. In other words, Bowley must have arrived roughly one minute after the shots. His timeline and Markham's are linked. You can not push back Markham's times and not do the same with Bowley's.
We know that the distance Bowley had to drive from the school where he picked up his daughter to 10th street is 6.3 miles. I know this for a fact as I drove the distance myself, but you can also check it on google maps if you don't believe me. A 6.3 miles journey in normal traffic would have taken him about 13 to 15 minutes, which fits perfectly with his arrival at the scene at around 1:10.
Maybe you can help me out on exactly WHERE on Jefferson Blvd. her bus stop was actually located. Maybe I'm not thinking of the location correctly. I'm envisioning her bus stop being right at (or near) the corner of Patton Avenue and Jefferson Boulevard. Is that correct or incorrect?
EDIT -- I see now that the CD630 page I linked above does say where the bus stop was --- it was "at the corner of Patton and Jefferson" (per CD630). And there's no way it takes 3 minutes to walk that distance.
You are right. From 9th street to the bus stop is two blocks of each around 400 feet. It would have taken around 5 minutes to walk that distance at normal walking speed.
