We call that Sleep-wake-junk.
From the Wiki:
Clusters of apnea and hypopnea events concentrated mainly around periods of sleep-wake transition. In general Sleep-wake-junk (SWJ) is not regarded as "real" since they do not occur during periods of sleep, but may be during semi-awake periods or "dozing".
I would hold with those settings for awhile as long as you "feel" ok. I'm sure Gideon will be around to advise.
