It is correct to say that it is possible to 'defer' assigning 'DTM = m', i.e. a) not doing it at the first possible retrograde cycle, b) indeed, doing it in cycle 'm+c' where c = 0 or 1, I forget The Wu/Beal algorithm, published in the journals IS and ICGA_J, does so, and brings efficiencies in so doing. Past practice, including EN's, had been to set DTM=m as soon as possible, reducing it later if possible. To do so is not an 'error', because the algorithm is organised to include the possibility of reducing 'm' later. g
