How the relevant dimensions are measured
Routine
The routine question captures the actual daily pattern:
- Early to rise, home in the afternoon, early to bed.
- Late riser, late home, late to bed.
- Non-standard shift (night work, rotating hours).
- No fixed pattern — changes week to week.
The incompatibility between someone who wakes at 6am and someone who regularly arrives home at 2am is not a personality conflict — it is a schedule conflict that is predictable in advance and avoidable with the right matching.
Noise level
The noise dimension covers how sound is used in the flat:
- Silence preferred most of the time.
- Background sound is habitual but not at high volume.
- Normal sound use, including high volume when the moment calls for it.
This covers music, TV series, work video calls, phone calls on speaker. A remote worker who needs a quiet environment to concentrate and a flatmate who works from a café and comes home to relax with loud music are not incompatible as people — they are incompatible as flatmates in a two-bedroom flat without soundproofing.
