Reporting - Accurate duration of meetings

I noticed that when downloading a Past Meetings report, there are only records of meetings where at least 2 participants were involved. Does this mean that if a host waits for the invitee and the person doesn't show up the meeting duration isn't recorded? The aim is to prevent false positive meeting duration time in reporting.

More important, when a zoom meeting is recorded.. does the duration time of the event includes the time that the host is waiting alone on the meeting room or does the recording clock starts ticking when the invitee joins?
