hmm, this was the meaning of -V in the very first beginning
of LAME's VBR code.
Actually you influence the absolute threshold of hearing aka ATH
and the masking thresholds computed by GPSYCHO. VBR tries to
avoid distorted bands, but sometimes, when there are not enough
bits, they will survive.

This is a little bit problematic, because the number of distorted
bands does not tell you the weight of distortions you will get.
What do you think sounds uglier:
20 distorted bands, each 0.1 dB
or
1 distorted band by 2 dB
