View source for Efficiency

There are many actions in ''Mush'' to which an '''efficiency''' is attached, given as a percentage. 
They can be classified into two categories:

* '''''Progress''''' actions, which are always successful, and are used for a greater task. The efficiency of all participants sums up, until 100% is reached and the task is complete. 

* '''''Random''''' actions (repairing something, shooting someone, etc.), which may fail: the efficiency is the chance of success.

In both cases, the efficiency you get varies depending on many factors: the action itself, skills, items in inventory, broken equipment, etc.

== Progress Actions ==

{{Main|Relaying}}
For several of such actions ([[Research]], [[NERON Projects]], [[PILGRED]]) the efficiency of any character '''drops''' after each progress, and is only reset to its base level when ''another'' character does the same action: ''relaying'' is thus needed. 

== Random Actions: Success Chance ==

In most cases, a failed random action will only generate a {{notification|private log}} but will, however, '''increase the efficiency''' by half or less. 

On the other hand, '''any other action consuming {{ap}}''' will '''reset''' the efficiency to its base level. Including  converting {{ap}} into {{mp}}. On the other hand, changing room when {{mp}} is available, lying down or eating do not consume {{ap}} and do not reset the efficiency. 

The maximum efficiency is of 99%, meaning that a random action can ''always'' fail, even after 10 unlucky tries in a row.
