I've had few upgrades since LS1010+VXR network and there is a
statistically relevant correlation to more bandwidth demand related to
the upgrade cycles. If you remove the heavy users, you can skip entire
cycles, putting your CAPEX in 50%, 33%, 25% of less of what it is.
Also your wave and transit costs decrease rapidly over time, as they
become cheaper faster than your user traffic increase, if you
cherry-pick the lowest 70% users.
Consumption is a significant cost driver.
