[Eril-l] Considering an all-campus Kanopy PDA subscription

[Cynthia Harper]

So trying to figure out how quickly our 250 students and faculty  would run thru our budget for a Kanopy PDA program, I calculated this: (I've excised the actual price because I'm not sure if that is  quoted differently per institution?).









2/month limit, thru budget in 3 months





250

people



250

people





5

films per month



2

films per month





12

months



3

months





6.5%

chance this is a film already seen by 3 other (visits or users?)

6.5%

975

Triggers



97.5

triggers





$          .00

per trigger



$          .00

per trigger





$  .00

annual cost



$    0

annual cost

















































































































































So thinking about the 80% rule distributed across a group of films







This probably overestimates the trigger%:











1 use

2 uses

3 uses

triggered at 4

5 or more uses

sum

# with this many uses

                      80

                                                      40

              20

                      10

                                               5

           155









6.5%






I'd be glad to hear from others who have made/are making this decision and what your experience or calculations show.
