ZoneAwareLoadBalancer why is default is 0.2d

[nantebi]

Hello,
We are not able to understand why the default value is 0.2d in ZoneAwareLoadBalancer
triggeringLoad = DynamicPropertyFactory.getInstance().getDoubleProperty(
"ZoneAwareNIWSDiscoveryLoadBalancer." + this.getName() + ".triggeringLoadPerServerThreshold", 0.2d);

in our environment all the servers have load of Integer 2,3 ,5
The calculation is:
loadPerServer = ((double) activeConnectionsCountOnAvailableServer) / (instanceCount - circuitBreakerTrippedCount);
assume that we have 1 instance and circuit is 1 and we have few connection at any moment it means that our loadPerServer will be much bigger than 0.2

Do we miss anything ?

We don't want to filter those zone with this low load ?

Any hint will help us.

Also we have tens of services and we don't want to change the value for each one of them.
Can the code be change that the default will be globally
