There are 5 zones of rebs at the 3 line.
There are about 12-15 bounces for each spot.
Have a level 1 C shoot at the 3 line in each zone for a long time while you reb until you memorize each bounce. Write them down to help. To start, you can let the bounces fall to the ground to see exactly where they bounce.
Practice kal points, the range to reb and chip range.
Map out the bounces and you will also see the best spot to stand at each shot release. Hint: left corner zone = more rebs come to left side.
Memorize all 75 bounces and you will have a huge advantage over your competition!
On a side note look out for the beast C WorldsBest!
