How do you lower the point at where Measurement changes suffix?

When you use Measurement, depending on the value given and the format, it will switch from a smaller suffix to a large suffix. Example: ft -> mi or m -> km.

Here it seems the suffix switches at 0.50 miles. I'm wondering if the "switch" point can be changed either higher or lower. It also seems the unit type doesn't make a difference.

struct ContentView: View {
    var body: some View {
        VStack {
            Text(Measurement(value: 805, unit: UnitLength.meters)
                    .formatted(
                        .measurement(width: .abbreviated, usage: .road)
                    )
            )
            
            Text(Measurement(value: 804, unit: UnitLength.meters)
                    .formatted(
                        .measurement(width: .abbreviated, usage: .road)
                    )
            )
            
            Text(Measurement(value: 0.5, unit: UnitLength.miles)
                    .formatted(
                        .measurement(width: .abbreviated, usage: .road)
                    )
            )
            
            Text(Measurement(value: 0.499, unit: UnitLength.miles)
                    .formatted(
                        .measurement(width: .abbreviated, usage: .road)
                    )
            )
            
        }
    }
}
