I would even go further to say that in cutting a bridge, a shade behind the
center line of the pin is desirable as invariably the edge of the bridge top
will gravitate toward the speaking length with some inevitable crushing of
the bridge top.

None, except that the notch edge isn't in the speaking length. With the
notch edge at or behind the pin, the pin is the termination as it should be.
If it's solid in the bridge, the sound is clean. If the notch edge is in the
speaking length, it interferes with the pin termination and makes the tone
indistinct and muddy.

A point I've tried to make for many years is that the pin is and should be
the termination, not the notch edge. The notch edge can only get in the way.
