Interesting article and well written too!
A few thoughts:
Regarding the percentage of JWs to the total earth population, you know that current JWs are already indoctrinated to dismiss that as irrelevant, after all God destroyed and entire world and only saved 8 souls in the ark. Also at Sodom and Gomorrah only 3 escaped Jehovah's divine wrath. So as compelling at your argumentation and logic are to a REASONABLE person, it is meaningly to a well-indoctrinated JW.
I think your arguments under the "Conversion Matches Gestation" section much more compelling and lucid. However, they are also sophisticated for the average JW to grasp.
Have you considered how the alleged JW growth compared to:
- Overall population growth - is it greater than, the same or less?
- Other religions growth rates - JWs like to cite their "growth" as "proof" of divine backing, yet from my brief perusal of the subject it seems that other groups are growing faster, (Islam, for example). Does that "prove" they have divine approval?
That being said, I especially appreciated the way you concluded the article and I applaud your efforts to reach those "being brave enough to give it careful thought"!
