Map marked in time segments along track - 7nm per minute at 420kt (sometimes a segment was just seconds rather than minutes).
I was always impressed with the pilots low level navigation skills with map and stopwatch - too low for any help from Tacan
but very enjoyable to be riding along at 250' AGL or so.
