Lame encoding algorithm quality

Hello everyone,

I have the following question regarding the "K3b Lame Mp3 Encoder" plugin version 5.0 used with K3b version 2.0.1:
When I choose to configure the plugins and open the "Advanced" tab in the configuration dialogue, I can set a counter which is connected to the quality. The labels suggest that this counter was supposed to be a slider ranging from "fast encoding" to "high quality" and since there's no further annotation it isn't clear to me which numerical value from 0 to 9 refers to what.
So the question is: Does 0 indeed refer to highest quality of algorithms used like it does with lame or to something else?
Thanks in advance for your help.

Sincerely yours,
        MoC
