Which door did Booth enter?

[L Verge]

Until about forty years ago, I had always thought Booth entered via Box 7, the same door that he had bored the hole in. However, I then began working with James O. Hall in developing the first of the Surratt bus tours over the escape route of Booth and found out that evidence indicated that Booth entered via Box 8.

I believe that Dr. Lattimer's description may be correct in where Booth aimed, but descriptions also exist that Lincoln leaned forward and turned his head at that second to see something in the audience - leaving the bullet to enter the left side of his brain.
