Sampling through typhoon weeks without skewing the year
Weather closures and work-from-home spikes distort occupancy charts—here is a fair way to sample.
Hong Kong’s signal No. 8 days empty commercial floors for good reason. If those days stay inside a quarterly average, owners see false troughs. Our seasonal briefings mark weather-affected days and report them as a separate appendix rather than folding them into the main profile.
The same care applies to the week after a long holiday. Lunar New Year recovery is gradual; treating the first two return days as typical weekdays overstates emptiness. We prefer a recovery window label so readers know the pattern is transitional.
When you only have access logs, ask whether remote badges or visitor tickets inflate counts. A clean definition—tenant staff vs visitors vs contractors—keeps charts comparable across buildings.
Fair sampling is less glamorous than a single bold chart, but it is what board members trust when deciding whether to reallocate floors.
