Many thanks for your comments Peter; I attempted the CT before reading the thread to interesting_signal as I wanted to make my own mistakes first rather than get some clues where other people have gone wrong and to confirm my understanding. Got a better idea now about the swinging overlap just one point in the swinging overlap entry for 203 R-N in the column 'points set or free' why do we not include 205R?
