Summary: Bug in VBR quality value?

Initial Comment:
I've just built lame-3.99.3, I'm now performing a series of tests on an audio clip, just tweaking the encoding quality via the `-q' and the `-V' switches.
Now in the resulting mp3, sometimes the quality factor doesn't change with the `-q' value! So, when encoding `-q 0 -V 5' the quality byte stores 50 and when I set `-q 1 -V 5' that byte is still 50. When encoding `-q 2 -V 5' the quality value is 50 as well and the same happens with `-q 3' and `-q 4'.
This value changes for `-q 5', `-q 6' and `-q 7', then it remains 43 (the same as `-q 7') for `-q 8' and `-q 9', why?
Is the same quality used under some circumstances?
