Local Chemistry in practice.
Mileage alone does not define nearby
A short straight-line distance can hide a river crossing, slow transport or completely different sides of a city. Local discovery needs neighbourhood and route context.
Broad city areas make that distinction without claiming to know anyone’s precise position.
Availability turns proximity into possibility
Two people in the same postcode area may never share a free hour. Someone slightly further away may follow the same commute or weekday rhythm.
Profiles that include a normal time window create more useful local relevance than an ever-expanding radius.
Repeatability matters for ongoing arrangements
A route that works once for a special occasion may not support regular chemistry. The desired frequency should influence how wide future discovery becomes.
Start with the journey you would actually make, then describe the arrangement that could realistically fit within it.
