The song Dead Enough for Life by Icon of Coil came on my Pandora, and I heard the line "efficiency of prayer," which made me want to see if anyone had written any snarky/satirical articles about how to "calculate the efficiency of prayer." Unfortunately there were no(!) Google search results for the quoted search terms.
A rough estimate could be calculated with the following simple formula:
Percentage efficiency (or perhaps "miracle rate") = (Number of times prayed for certain thing) / (Number of times the desired outcome has occurred) * 100
My guess is that "miracle rate" for bringing back people from the dead approaches zero, but may actually be a real positive number for self-fulfilling prophesies, like a job interview going well.
Good luck!
