1) Adams is recorded as seeing people, and none of the other 3 saw each other, means that the piece of data is uncorroborated, taken with her later denials and other testimony of an early descent makes it an outlier.
What other testimony of an early descent?
2) There was only 4 woman in that office, the other people were in other south facing sections of the 4th floor. Garner arrived in time to hear the other girls descend and then see Truly and Baker come up. However T&B didn't see the girls om the stairs, so they must have descended and exited before T&B started up the stairs. If so either Oswald is ahead of the girls and loiters in the 2nd floor lunchroom or sneaks past Garner on the 4th (moving quickly on wooden floor boards)
You are right. There were only four women in that office.Hollies and Foster were in another room.
Styles was adamant that they never left right away. No less than a minute she said. If they did leave early and missed Truly and Baker then they must have really been going. And in three inch heels at at that. Oswald wouldn't have had to sneak past Garner because he would have already passed by before she went back into that area. With the speedsters in their three inch heeled shoes clop clop clopping on the wooden stairs, Oswald was able to follow behind, with any noise that he may have been making being drowned out by that of the speedsters.
3) There responses were not recorded, so if they were asked, are you saying the information was suppressed or just counted as unimportant. The positions were accounted for at the time of the shooting but not in the 2 minutes that followed. The crucial window where any shooter from the 6th would need to descend.
The information was counted as unimportant. I seem to recall Garner saying that she was the first to go to the back after Adams and Styles had left.
