Agree with Alex. Some kit can list the channels allowed by auto; but if not then you’re possibly being very unfair to your neighbours, straddling two or even three standard channels (if you’re greedy, on 40 MHz twin channel). Using a four channel (1, 5, 9, 13) pattern is quite a reasonable idea in a congested area but all neighbours have to agree on it and many wouldn’t have a clue, so politically challenging, so best to stick to the standard 1, 6, 11.
