Here some things I forgot to mention, maybe the penguin team can merge this review or just publish
both.
I wanted to clarify that this method is psychologically by nature and only as good as
the performer is. Meaning Derren Brown would probably be at 100%. Most others with experience should
be at around 90% to 95%.
If you have no experience you will be significantly lower and
become frustrated.
Just wanted to make this 100% clear!
