Sound forge 7.0 has VU meters in addition to peak reading.
For the VU meters, we have these settings:
Traditional VU
Logarithmic VU
Extended VU
UK PPM
EBU PPM
DIN PPM
Nordic PPM
The ballistics I used for this file were that of Traditional VU. The meters can be scaled so the actual indication over +3 will read to the right.
RMS power on the otherhand cannot exceed 0 as we all know.
I believe their are some pretty accurate plug-ins available for VU that you can install to see where your reference level lays. Typically, very hot CD's will reach as high as +8VU but never have I seen anything above 11 and this 14.3 is simply "crazy"
The VU scheme that sound forge uses may be an "approximation" of actual VU. I would like to see the code behind the readings. It may give some valuable insight as to how they are deriving the figures. I am dabbling in this code a little bit to understand the actual design nature of plug in's. I get lost pretty quick in machine code.

0 VU is +4 dbm and represents a voltage level of 1.228 volts (1kHz, 600 ohms).

Correct. And also 0dbfs should be 0.775V
