Well, many indian tribes shot with a floating anchor and a short draw and kept their families alive with them. The more you shoot the better you will get at it.
With that said, I'd personally not shoot one due to the tendency for development of target panic/freezing early. It took me several years to break my own freezing early issues. Also, you will not get nearly the ballistic performance with the short draw as you will with the long. A solid anchor point is very much associated with accurate, consistent shooting.
