Well I will look up for my sources but I also read the theory that the Eberschnauze could have been more the result of how masses of human in movement behave rather than a wedge formed on purpose.
In that case it would have been more a arc or crescent shape. This sounds quite compelling to me since I don't see any point in having one single guy in the front. Wedges work for dense materials but in a crowd the first guys would be very easy to slaughter... imho
