If Baker enters the TSBD in 30 seconds, and there are people behind him, in front of him, and to the sides of him, how does he converse with Truly, make it through the lobby and then cross the 1st Floor in only 30 additional seconds? He doesn't. Plus, you claim that Baker can Not see Lovelady and Shelley crossing the same 1st Floor in front of him, due to the 1st Floor being cluttered. This means that Baker and Truly are not crossing the floor inna straight line. This only increases the time it took them to navigate their way across the floor. I also believe you do not appreciate how large the footprint of the TSBD is. Crossing a floor is a good walk, especially if the floor is cluttered and Baker has to follow Truly as he zig-zags across it. 30 seconds to go from the TSBD front door, talk with Truly, fight their way through the throng all around them in the lobby, and then navigate across the entire 1st floor is too quick.
If Baker enters the TSBD in 30 seconds, and there are people behind him, in front of him, and to the sides of him, how does he converse with Truly, make it through the lobby and then cross the 1st Floor in only 30 additional seconds? It's easily done.
Yet again, we are dealing with your inability to visualise things in a realistic way or to think things through properly.
You don't have a "tick tock issue", you have a thinking issue.
You also need to familiarise yourself with the evidence.
The distance they have to cover is no more than 110 feet. They don't walk , as you suggest, but "trot". At 5mph this is faster than a walk but slower than a run. Also, they don't have to zigzag, as you suggest, they travel straight ahead for about half the length of the building then travel diagonally to the area near the elevators.
110 feet can be covered can be covered in 15 seconds at a trot (there's 5280 feet in a mile if you are going to do the calculation).
After you've done the calculation, get yourself a stopwatch and time the following
imaginary interaction:
Baker: Who can show me where the stairs or elevator are which will take me to the roof?
Truly: I'm Roy Truly, building supervisor, I can take you to the roof.
Baker: Let's go!
I make it at 10 seconds.
This even leaves enough time for Baker to run into the back of Truly at the counter.
Remember, the timings I've given are an approximation but, even so, they still stand up at the moment without any change.
There is no "tick tock issue", as you put it.
The arguments you've raised against my proposed timeline reveal nothing wrong with the timeline but plenty wrong with your ability to visualise reality.
You must see the ease with which your objections are being dealt with and you must concede that, after all your objections have been dealt with, the timeline is valid.
