My personal estimates are similar. For anyone that followed Falcon 9 development (from the first Falcon 1 launches), it’s really similar. I remember boom after boom until one day they cracked the problem and reusable boosters became the status quo.
I got tingles when the first booster landed on the drone ship, because I knew access to space had just changed in a fundamental way.
