Like 5 permission requests = 80% drop off. Also, can you really correlate installs with permissions (it might be something else that is putting users off, which consequently correlates with the drop off in installs -or how did you statistically determine causality which prompted FB to warn developers to reduce the number of permission requests? and do you see a change in behavior after having asked developers not to ask for too many permissions?).
