A.R. 200 paraphrased -
A1, after
1) receiving a pass
2) ending his/her dribble
jumps to attempt a try and voluntarily throws the ball to the playing court and is the first to touch the ball.
Ruling
1) traveling violation as A1 lifted their pivot foot before beginning a dribble.
2) double dribble as A1's throwing of the ball constituted the start of a dribble.

I guess my rule of thumb holds true as the pivot foot movement occured with A1 in possession of the ball.
