RT literatur mostly methinks. Replacing WCET with a statistical model of
sorts is not uncommon, the argument goes that not everybody will have
their worst case at the same time and lows and highs can commonly cancel
out and this way we can cram a little more on the system.

Typically this is proposed in the context of soft-realtime systems.
