Well, exactly. I don't know if the complexity was worth it or not because I'm not an expert. For comparison there were apparently 30 NK-15 engines on the first stage of the N1. (from Wikipedia of course) What I did read somewhere was that they had a production line and they filmed it all so they could see what happened to any engine during production and go back to the recordings if something went wrong with it. I'm not a Russophile at all, but I suspect that there were clever people who solved problems and others quietly took note of it.
