This can be assisted with a flywheel - a weighted wheel designed to help maintain speed during shooting. With a flywheel, it will take longer to spin up initially, but the wheel will slow down less when it fires a disc. This helps to maintain a constant speed as you shoot.
You speak as if we're not already doing this
