My team and I tested our catapult, and found that the spread between disc’s is a lot, the top disc almost always flies too far, and the bottom disc always undershoots the goal, is there a way to reduce this spread and keep the disc’s together in the air. We’ve only got all 3 disc’s in sometimes, when it’s in a very specific spot, is there a way to have more flexibility with the range.
I would recommend recording and watching your catapult in slow motion and observe the discs path. Then try various methods to mitigate the spread and don’t forget to put it all in your notebook!

Sadly, from what I’ve seen there really is no clear-cut way to fix catapult grouping (like a “one solution fits all” sort of situation), rather you should take countless slo-mo videos and go with your gut. It’s also a good idea to see what other teams have been doing to mitigate catapult grouping issues, but take note that not all solutions will work for your robot.
record cata in slow motion, see what happens, either reduce your tension (rubber bands or latex tubing), your hardstop placement ( to increase or decrease angle of release) or your actual robot placement (closer or further from the goal)
