Being able to clone myself and sync with my clones is something I've thought about since I was a kid.
I don't think increasing the number of clones would ever allow me to satisfy all my wishes. The number of things I want to do increases with the number of experiences I have in a non-linear way. If I want to be satisfied I need to be willing to accept all of my wishes will never be fulfilled.
To answer your question specifically: 0 clones
