XMLTV describes a start-inclusive, stop-exclusive interval. Adjacent entries can share a boundary without representing simultaneous programmes.

Why two XMLTV entries can share one timeslot deliberately
XMLTV can represent several programme items in one slot using clump metadata. Inspect the grouping before deleting an apparent duplicate.
Why a freshly converted guide file can still contain older listings
The XMLTV listings date represents source-production context. A new download or conversion time does not automatically make the underlying schedule fresh.
Why a guide supplier’s information page is not necessarily the XMLTV feed
XMLTV distinguishes a human-readable source-information URL from a data-source URL. Copy the value intended for the actual consumer’s documented input.
Why averaging two download speeds can give the wrong total rate
For consecutive transfers, divide all transferred bits by all elapsed time. An unweighted mean of the individual rates can overstate the combined result.
Why half a ping time is not a measured one-way delay
Dividing round-trip time by two assumes a symmetric journey. The result does not measure either direction separately.
