Since this really isn't that important, well except for anal retentive nitpickers, in the end I took Jerry's approximation from Altgens to Jackie's door/Kennedy's head to be about 30 feet so I divided his overall measurement into 3 pieces and hence the overall proportional distance is about 18-19 feet. If you really want to figure it out exactly to an inch then be my guest and forever more you can be the hero of this insignificant factoid.

Thanks, Mr Fallacious Arguments
So, when asked a simple question, you go full ad hominem " anal retentive nitpickers", and then go to the absurd, " exactly to an inch" , and then try to minimize, " insignificant factoid".
Yet, you never get around to answering the question.
Did you factor in the width of the street?
If so, please show your work.
Thx.
