Multiplex Shuffle experiments

Started the practise session thinking...'What could be the easiest 4 ball pattern to use shuffle type throws?'
Got some ideas but none were one day, same day learning type things needing more practise days so ended up with multiplex. Cheating but still nice.
This one based on 622[54]1

But how to get a shuffle throw through the split? Timing is more precise but so good when it works for any pattern. So much potential. 

Or just throw a 5 through the split, also nice.
