, with apologies to Edward Tufte, and anyone who has to sit through these dreadful things.
I have come up with a way to calculate the Divulged Useful Median Basline Information quotient of any Power Point Presentation.
The variables in question would be:
p: Total number of slides in the presentation.
g: Pages without text, or pages that are not read from the presentation, or intelligently designed slides with usable information not being spoon fed to you.
F: Spoken phrases NOT from slide, excluding "Next slide, please"
T: Total number of spoken phrases, not including questions
H: Relative value of handouts/notes--complete presentation copies or useful info? (general scale from 1-3 would work, I think, if standardized upon by everyone. For purposes of this discussion, we'll go with a number between 0 and 1, as a decimal equivalent for a percentage. Limiting the number of practical choices, though, to pre-defined answers would be in the best interests of standardization)
S: Presenter's grasp of the presentations' main language (for my purposes, English) in a flowing, lively or informative manner (again, 1-3 would be best, but for calculation purposes, 0-1)
Precentage of Content Related Across Presentation (C.R.A.P.) = ((p-g)/p)*100
Percentage of Spoken Heuristic Information Transferral (S.H.I.T.) = ((T-F)/T)*100
Divulged Useful Median Basline Information quotient is then (DUMB Info) = (S*100 + H*100 + [S.H.I.T.] + [C.R.A.P.]) / 4
