Power & PAM.

I apologise if this has been looked at before - if so please refer me to the thread.
I hesitated whether to post it here, or under "Ask Spelly", but it is not a pure SANFL question.
Three questions: Does anyone know?
1. What percentage of Power members are still or are former Port Adelaide Magpies members?
2. What percentage of Power supporters are still or are former Port Adelaide Magpies supporters?
3. Did PAM membership drop, and by how much, when the Power was formed to enter the AFL?
