Dava Sobel takes the micky of Maskelyne an others astronomers like (Hayley, Newton, etc..) who defended the moon distances system when she pretends being an "oraculus" when she asks:
"..and what they do when its cloudy?" here is my answer Dava Sobel.. the same as with the chronometer system "waiting the clouds to disappear".. for the chronometer system needs some astronomical sights (as with lunar distances) to calculate the local hour..
I think Dava Sobel refers to Captain Sumner system of LOP inference in cloudy days, which can be applied as well to the lunar distances..
Lunar distances have disappeared when Marconi crossed the Atlantic with radio signals in 1906 that allowed chronometers to be perfectly synchronized..
