Why timing affects how measurement results should be read
Launch library · evergreen read

The exact same underlying result can look genuinely quite different depending on precisely when it is measured, since coverage, sentiment and audience attention typically follow a natural rise and fall around a campaign's key moments rather than remaining constant throughout its entire run from start to finish.
Measuring too early in a campaign's life can genuinely understate its eventual effect, particularly if the strongest coverage actually takes real time to develop and build momentum, while measuring too late can miss the campaign's genuine peak entirely, having already moved on to a later period when attention has naturally settled back down again.
Understanding these underlying rhythms helps a practitioner choose genuinely sensible measurement windows and interpret results honestly, rather than reporting a single snapshot that happens to look favourable while quietly ignoring the broader pattern that a longer, more considered view of the full timeline would actually reveal to anyone willing to look closely.
