I've been normalising every track I've encoded to 93% to prevent the clipping messages in MAD. Now I know that some albums even clip at this setting, but 95% don't. However, I was encoding an album today "Yoshinori Sunahara - PAM AM Sound Of 70's" which I had to take right down to 78% before the latest MAD plug-in would count zero clipped samples. Can this really be right? Can someone explain how the filtering process can make such a large difference?
You've probably been on this list long enough to recall the clipping thread, but in case not, start here:

There's also some good info here:
A reduction of overall amplitude to 78% works out to be only about -2.2 dB, which really isn't an excessive amount of attenuation. In fact it's probably about par to avoid clipping in a lot of heavily compressed music these days.
