What he means to say is the it can be confusing at 1st but I can tell you from experience with, "Stand up monte", The secret is to use double thick cards so you can FEEL proper placement of unique items.
It's funny to me the Effort to Outcome ratio.
If you think of a musical instrument and a new piece of music. Yeah it will take several hours to play the music with heart.
If you take a girl on a date, you usually have 7 hours of logged date time before you reap various rewards.
So 7 hours from practice, rehearse, to performance is appropriate. Especially if you want your audience to reap what you've sewn.
It's all about perspective - Plaudits.
