invictus005, I believe Baerwald is a real alignment. This link is for his AES paper of 1941. He acknowledges Lofgren who developed a similar alignment in 1938.

Anyway, it is common to see Baerwald identified for this alignment. I'm not certain if it is precisely the same as Lofgren A, at the very least they are nearly the same. You likely know Lofgren later developed a different alignment known as Lofgren B.
The point is that multiple alignments have been developed over the years for pivoted arms based upon minimizing distortion within specific areas of the transcribed arc. It is up to the user to decide which suits their preferences the best.
