# perfomance modeling - t6p355rP1-2

Rule P1 -- perfomance model successful:
if agreements/completed > perf-threshold

Rule P3 -- path model lost:

  then path-state = OK 

# confidence modeling - t7p356rC1-2

Rule C1: 
if answer was low-confidence (either agree or disagree) 
  then decrement conf-value

Rule M11:

Rule M15:

  and increase control
    then avoid intervention
Rule M16:

  and increase control
    then encourage independence
Rule M17:
if encourage independence
  then avoid intervention 
Rule M18:
if help-state = rejected
  and help-skip-next = no (needs to be fitted to "skip next help" or whatever)
  and respect control
    then avoid next intervention 
Rule M19:

  and help-skip-next = yes (ditto)
    then avoid intervention
Rule M20:
if help-state != requested
  and not increase confidence 
  and not stimulate curiosity
    then share control
