    discussing the real advantages of new takes is subtle enough, but weighing these against the benefit of reusing existing know-how for both current and future projects is very tricky. in applied maths this is the problem of subtracting two large numbers (catastrophic cancellation): your result is unstable, very sensitive to assumptions

      Catastrophic cancellation
      In numerical analysis, catastrophic cancellation is the phenomenon that subtracting good approximations to two nearby numbers may yield a very bad approximation to the difference of the original numbers. For example, if there are two studs, one L 1 = 253.5 cm {\displaystyle L_{1}=253.5\,{\text{cm}}} long and the other ...
