    Possible limitaion for lunar distance measurement

    It was some time since I discussed accuracy in lunar measurement with Frank Reed and George Huxtable. I think this matter is satisfactorily settled – at least from my perspective. However, some weeks ago I was approached by an old collegue of mine raising a question related to lunar distance calculation, which I have not considered so far. My fellow made a reference to the German Manual of Navigation issued 1906 ( title: Lehrbuch in Navigation). On page 386 in this manual it is stated that it is only possible (or feasible) to use the lunar distance method if the distance is between 70 and 110 degrees. The formula used is the Dunthorne formula. There is no explaination in the manual why it should be like that. After solving quite many lunar cases I have not found any limitation as indicated above. Is there anyone who have any answer or explanantion or thought about this.
