Not a big fan of this. It's just not an effect that's going to get big reactions. Even an
unsophisticated spectator understands the general concept of false counts and displays. If you
execute this competently, you will get a reaction like, "You were very skillful in disguising which
cards you were holding", rather than, "Wow, I have no idea how you did that!"
For some
people, this might not be a bad thing. All you need to know to perform this is an Elmsley Count,
yet to a layperson, it might give the impression that more advanced handling skills were required.
So, if your goal is to impress someone with how you can handle cards, this might suit you; if your
goal is to fool a spectator and leave them baffled, I think you need to look elsewhere.
