[vorbis] RC2 better than RC3 ???

Since 1.0rc2 was released i have found that ogg at 64k
sounds almost like  mp3 at 128k (in 95% of the 3000 files i encoded...)

I tested 1.0rc3 and 64k bitrate (quality=0.0) gives
less good quality than before.
And bad : it takes longer to encode !
(1.7x vs. 2.0x on a P2/500MHz)

Effectively 64k ogg files encoded with rc3 are smaller than
files encoded with rc2.
I hear people debatting on how satisfied they are encoding
files at quality=3 or 5 or 10 !

The way i think vorbis format is superior to any other format is not
quality :
you already get quality with all other formats at medium/high bitrates
Ogg gives quality at very low bitrates, and THIS is the most
important to my eyes !!

Anyway i need to encode at least at 72k (quality=0.5) with rc3 to
have the same feeling i used to have with rc2 at 64k !!!
