Walkscore is biased towards certain kind of amenities.
Restaurants, Bar, Caffes and Entertainment are 4 separate categories out of 9.
Al the rest is lumped in either parks, schools, errands, shopping or groceries.
When you look into subcategories, you see things like 'health' is subdivided into Fitness, Yoga, and Hospitals/Clinics. In that order. So a full blown hospital, with ER, hundreds of beds, advanced scan, maternity, outpatient services and dozens of doctors offices weights like ... a hot yoga saloon.
