Matt, Thanks for providing the raw count. A quick and dirty analysis shows that: In the worst case scenario (0% efficiency), each technique would apply to every category, so the categories mean nothing: # of icons = # of techniques * # of categories In the best case scenario (100% efficiency), each technique would belong to only one category, so: # of icons = # of techniques So, for the whole document: > Markup Editing Tools: 96 > Multimedia Creation Tools: 75 > Content Management Tools: 78 > Programming Tools: 55 > Conversion Tools: 6 # of Techniques: 106 BEST CASE = 106 Icons WORST CASE = 530 Icons ACTUAL = 310 Icons (~52% efficiency) *EFFICIENCY = 100% - (ACTUAL - BEST CASE)/(WORST CASE - BEST CASE) But some guidelines are more efficient than others: > G6: > Markup Editing Tools: 12 > Multimedia Creation Tools: 12 > Content Management Tools: 12 > Programming Tools: 12 > Conversion Tools: 0 > None specified: 2 # of Techniques: 12 BEST CASE = 12 Icons WORST CASE = 60 Icons ACTUAL = 48 Icons (~25% efficiency) > G7: > Markup Editing Tools: 23 > Multimedia Creation Tools: 12 > Content Management Tools: 10 > Programming Tools: 7 > Conversion Tools: 0 > None specified: 1 # of Techniques: 28 BEST CASE = 28 Icons WORST CASE = 140 Icons ACTUAL = 52 Icons (~79% efficiency) Unfortunately much of our efficiency is provided by the fact that the Conversion Tool category is used just 6 times. Leaving out this category, the efficiency scores are: All techniques: 38% G6: 0% (all techniques apply to all 4 categories) G7: 71% -- Cheers, Jan /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ Jan Richards User Interface Design Specialist Adaptive Technology Resource Centre (ATRC) University of Toronto @: jan.richards@utoronto.ca P: (416) 946-7060 F: (416) 971-2896 /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
