Similar to the above options, these options override the default behavior
of Tor's (**currently experimental**) path use bias detection algorithm.

Where as the path bias parameters govern thresholds for successfully
building circuits, these four path use bias parameters govern thresholds
only for circuit usage. Circuits which receive no stream usage
are not counted by this detection algorithm. A used circuit is considered
successful if it is capable of carrying streams or otherwise receiving
well-formed responses to RELAY cells.

By default, or if a negative value is provided for one of these options,
Tor uses reasonable defaults from the networkstatus consensus document.
If no defaults are available there, these options default to 20, .90,
.70, and 100, respectively.

If this option is set to 1, Tor might connect to entry nodes over
IPv6. Note that clients configured with an IPv6 address in a
