That does seem like an interesting feature. The job
I'm working on now has transient spikes that are
probably +6.0dbfs above the average. I used the TAP
Scaling Limiter post fader to deal with them. This
does a good job.

Do you imagine that spikes of this extreme are beyound
the scope of the peak allowance mode?

I assume they are. Otherwise, we're probably dealing
with something that's aggresive enough to become
audible if the user isn't able to adjust it. I don't
really know and am simply speculating.
