> Achieving a 10x improvement over the previous generation usually can't be done without doing something new It is definitely possible if the fixed cost(e.g. R and D, manufacturing capability, testing infrastructure etc) is majority of the cost and scaling up doesn't increase them linearly. Cost of raw materials like fuel or building material would be negligible for Apollo or SLS in comparison.
