OK - what do you do here?

[Mark Padgett]

Two person mechanics, FED rules. A1 shooting the second of two free throws. You are trail. The ball hits the rim and bounces away staying on the court but your partner, at lead, blows his whistle and gives the "swerlie" mechanic with his hand and says the thrower violated by the ball not hitting the rim. You tell him you had a clear view of the shot and it definitely hit the rim. He says OK.

Do you go to the AP or use POI? If you think you should use POI, then what would it be?
