It has been demonstrated that the walk is achievable in under 12 minutes.
From a Steve Howsley post in another thread...https://www.jfkassassinationforum.com/index.php/topic,1349.msg37231.html#msg37231Using google maps... the shortest possible actual driving distance is .8 miles.To do any better, you must shape-shift into a crow.3 miles an hour is quite a brisk walking speed. Thus the time/distance calculation would be .8 X 20 minutes = 16 minutes. I did walk the route years ago as a younger skinny guy. I took [oops] a wrong turn and it took me 18 minutes. But the main thing that made me feel weird about that trial is..Where in hell am I going and why am I going that way?
3 miles an hour is quite a brisk walking speed.
Not to anyone who has ever been on a treadmill.
Now, all that said, here is a general guideline on treadmill speeds: for most people 2 to 4 mph will be a walking speed; 4 to 5 mph will be a very fast walk or jog; and anything over 5 mph will be jogging or running. By contrast, an average easy walking pace is more than 20 minutes per mile (slower than 3.0 mph). A fast pace is under 15 minutes per mile (faster than 4.0 mph). If you already have a high fitness level, you may not be in a moderate-intensity exercise zone at a 3.0 mph pace.
It's always incredibly amusing to me when someone makes a claim and then posts evidence which in no way whatsoever supports their claim and then they celebrate in their false victory.
Precedent-wise, in Oswald's case: Brennan, East window, 6th floor, TSBD.
