But did those "internal docs" take the increasing power of colo machines (or rent) into account? The colo you buy next year probably is more powerful than the one this year. If you take AWS price decreases into account, you'd need to take increasing power (and decreasing prices) for colo into account.
Hetzner where I have servers increases the machine power (and sometimes decreases prices) every year.
