The only pieces I would lose would be a couple in between the pistons but I don't believe they were from a timing issue, I think its just when the pistons crush the melons they jump to the side a bit as well. I found if I changed the delay on the repeaters either way I would lose the stalks in between because the water would wash them away. It's worth playing around with, your welcome to download it and mess with it too. I'll get working on v2! Thanks for the feedback btw!
