It does seem that, whilst exposing what is going on to examination, all
these ideas are fudges. Surely it would be better to integrate the whole
thing into code ? Since what is beng stated is that two points in the survey
must, by the laws of physics, be at the same level, surely what is needed
is a way of just saying this in the survey data, and allowing the program to
implement the sorts of calculations that have been outlined previously ?
