Very much recommended, even if you skip or only skim the mathematical details in chapter 5, as I did. What I don't understand, is why the patent application was not objected in the secrecy order phase. Or was it secretly partly in the US, because the actual US patent apparently only covers the recommendation to pick your own P and Q, and not the actual mechanism itself. It is not clear to me what the last few sub-chapters are meant to show.
