I think you are being far too pedantic. The bush and trail surfaces vary greatly over the length of the Mundabiddi and trying to make them "consistent" will means that some are right and some will be wrong. The nature of the trail and site is not consistent so each should be labelled according to how they actually are. Don't change them until you have seen them. I have made the effort to visit all the trails I have marked and there is nothing more annoying than an armchair mapper ruining my work.
