Compare two illustrative timelines
Suppose a path transfers 60 megabits during a ten-second interval. Its arithmetic average is 6 Mbps. That total could arrive steadily, or much of it could arrive near the end after a long gap. The average alone does not distinguish the two patterns.
A player with limited stored media can run out during the gap even if later transfer makes the interval's average look adequate. These numbers illustrate timing, not a measured IPTV Canada stream or a required buffer setting.
Record continuity alongside the rate
Keep playback start time, pause times and approximate pause lengths. If a supported diagnostic exposes buffer state or segment timing, record what that field actually measures. Do not infer a ten-second outage solely because the spinner stayed visible for ten seconds; application recovery can add its own delay.
Separate an initial slow start from a stall after several minutes. The first may involve connection or authorization work before the buffer fills. The second describes a later continuity problem. Both need the actual requested item and player context.
Use the original viewing task
Compare the same permitted programme, device and route over a similar interval. A fast file download after the event is context, not a reconstruction of the earlier arrival pattern. Keep the date and time zone so the operator can correlate the incident with its own records.
If optional household traffic coincides with the gap, use one controlled pause/resume comparison. Do not change media quality, router location and player at the same time. A clean difference is more useful than another averaged score from a different workload.
Choose the next test from the gap
A repeated local-path difference can justify network investigation. A failure at one exact programme point across paths can justify a resource-specific report. A specific HTTP refusal should be handled as that response rather than folded into a throughput average.
A larger supported buffer can change tolerance and delay, but it cannot guarantee continuity under sustained inadequate delivery. Record any setting change and retest the original symptom. The goal is reliable arrival for the task, not merely a reassuring average collected over a convenient interval.

Does an average above the media bitrate prove smooth playback?
No. Timing variation, gaps, application behaviour and other constraints can still interrupt playback.
