I agree 100%, and probably there's a big misunderstanding here - the testcases that i've seen coming from the OakTable are not meant to reproduce the behaviour of running systems, far from that (they are not benchmarks in other words); they are experiments that focus on a particular subsystem of Oracle (say the parsing engine, the index machinery, the redo log subsystem ...) in order to

o illustrate the subsystem ("an example is worth 1000 words") o let you see that what's being said is real, not a speculation by the Author.

In other words, they are not different from a lab experiment about the Ohm law, that focuses on steady state electrical laws. Add to it an experiment about capacitors, another about the magnetic field ... and you eventually graduate and can go out in the business as an electrical machine developer or an electrical machine administrator. Without necessarily joining a college.
