I think people should practice their routines like crazy.
I think the punching routine is not that hard but somehow people are not able to do it.
Practice and do your bit, if you do your bit then that is one person we don't have to worry about.
Practice guys and I think the original yelling is ok. I made it as simple as possible to be done on the day.
Too complicated and too precise would not work on the day.
