Right you are; entirely my fault, and corrected now.
Sorry, and thanks.
Unfortunately, when it comes to rockets, a couple percent difference in performance means a huge difference in the first stage.
The Russians make quite good early-stages for their rockets - but they've long had trouble with the upper stages. The N1 being the glaring exception, even the first stage was big trouble... they just couldn't handle the necessary level of QA for such a complex design to work, at least not on the budget they were given.
It is if you have the right lawyers.
An Ada exception is when a routine gets in trouble and says 'Beam me up, Scotty'.
