Oub,
It's interesting that you did this research, thanks for that. I am not surprised it's aimed for 11 yr olds.
I actually mentioned it in another thread that I think WT is targeting pre teens....and have them baptised and trapped at a younger age than normal.
By the time a child is 14/15 they have already identified it's nonsense in many cases.....so less teens are getting baptised.
