It depends on what you are best at doing right now that will give you the best immediate results...
It's a combination of the two that give me my best consistant results. There are some girls that neither of the processes work on after they judge my character. They expect me to throw down my guard and become an AFC before they begin to lower their shields. than they let me return my old self after they realize how much fun it was in the beginning...
Being mysterious was probably Mystery's first take on seduction, his oild theories and current still hold the notion in the back of his mind since he repeats the idea to himself everytime he says his name. Than he goes off and runs a few routines and does some magic tricks and talks about all of his seduction teaching to people, completely obliterating his theory.
He teaches to take things in order though. M3 method style,you stay congruent with the setting and forcably bring the relationship to the next level.
so all in all from mysteries portion of the teachings... There isn't really ANY contradiction, just different usage to get to the same end result.
Acting like the situation is chill and stepping in to keep the frame in control will work to your advantage if you really are calm and collected. Doesn't work for me though, I operate in dynamic environments, so I only use this part of the game when it comes to certain girls.
Amping up the sexual nature when there it isn't even implied in the first place, is in essence the key to seduction. So it doesn't make sense to view this as a contradiction for any reason. Using sexual innuendo and teasing is a way to control the frame, just like being calm and stepping in when the time is right.
There is such thing as timing, and there is persistence, it's up to you and your strengths to determine which you choose for the specific moment.
I don't use either for any specific girl. I judge by her reaction and mix and match. I'm not so much into ONS anymore unless I am in a party environemtn and drunk, so I aim for a laidback approach in most instances. When I am out with my friends and having a good time though and I have nothing to worry about, I let the enrgy flow and I unleash the innuendo and the C+F jokes.
For me it depends on my mood what combination I choose.
