VTA is typically around 20 degrees today.
The geometry of this is clearly defined by Risch & Maier, who wrote the seminal treatment of this:
"VTA is the angle between the surface of the record and the line described by the contact point of the stylus in the groove and the pivot point of the cantilever."

The current standard VTA seems to be 92 degrees.Oh, no, you’re confusing VTA with Stylus Rake Angle.
