The most probable outcome turns out not to be the given parameter, but half of that number, as can be seen in the graph to the right. rnz is used for the following purposes: * rnz(100) is the time that one must wait after invoking an artifact before invoking it again. * rnz(10) (or rnz(25) when first building a level) plays a part in determining when a corpse disintegrates. * A number of rnz calls are used in determining the prayer timeout. In particular, the timeout after successful prayer is rnz(350), with a penalty of rnz(1000) added if you are crowned or have killed the Wizard of Yendor. If you have killed the Wizard and are also crowned, the penalty is doubled.
