I concur with DoubtingBro. I think those percentages are pretty accurate.
I recently had a conversation with my mom (a die hard JW, pioneer for the past 30 yrs, had about 30 of her students baptized) about the May 1st QFR and was surprised by her response. She said the newer members of the GB are too young to truly be "annointed" and she feels it's their influence which caused the writing of the article. She then through me for a loop stating that it's a shame that articles such as these give fodder to the opposers of "Jehovah's Organization" and she doesn't appreciate them. So there you go, a die hard JW doesn't believe the newer GB members are truly "annointed" but STILL believes this is "Jah's Org." I guess she falls in that 40% group.
