1) YES, we had a high rate of bounce back for relatively long shots.
This affected the outcome of some matches for us.

2) The goal stayed the same as initially designed, we would not expect
it to be changed. If it was changed, one might reduce bounce back
for some trajectories, while increasing it for others.

3) We have witnessed bounce back at every regional we attended.

4) Bounce back is part of the game challenge. The chance of bounce
back depends upon the trajectory. We found that high angle shots from
closer to the goal minimzed bounce back, and this is a good thing
for the best shooting positions for most robots. Once we gathered
enough experience with bounce back we learned to avoid shooting
positions that increased the rate of bounce back unless the game
situation forced shooting from these positions.

Our shooter fires at 45 degrees, with a wheel speed that is set by
the range information obtained from the camera. An RPM limit that
produces 12 m/sec is enforced in the software that controls the wheel
speed. Getting bounce back does not mean that you are shooting to
fast. It has more to do with the specific tractory of the ball as it
enters the goal than the speed.
