So, to get maximum throughput on a 30mhz channel, it would be required to lock down all but the last two channels to avoid the backoff requirement? Is there a way to leave DSO on, with all channels available, but set a preference to the last 2, given that unless the first sets of channels are busy, they will sit on the lower, with the backoff requirement, impeding the throughput
