In practice I generally see the abandoned work fraction dominated by much less interesting and much less valuable poor planning decisions, false starts, and misalignment between teams. Genuine high-value risk taking is typically already so rare in most organizations that it doesn't even show up significantly in a count like this. Equally importantly, when those genuine risk taking activities are terminated they typically happen in the form of an experiment that reached a customer at some level as part of the decision to terminate the effort. If it reached a customer in some manner like that it's not in the bucket of tasks started that never reached a customer.
