It will surely have a negative effect for you if she faked her 'female to male interest'
right from the beginning.
What are some of your most efficient ways of dealing with/filtering out, these types of
girls?

screening hard

direct open (if she doesn't open, she is obviously not interested), and start screening (qualification and escalation),

don't qualify and screen to get a girl to like you, screen to actually screen, and start actually screening, if they suck, on to the next one

you can ask yourself, what do you want, an ego boost and a few flaky phone numbers or girls that end up going no where and end in a waste of time, or a cool girl who you have things in common with, who is what you were looking for, and actually is interested in sleeping with you?

ask yourself what you want in a girl and what you are looking for, and actually go looking for it and try to find it, if you want a girl who is fun who has a sense of humour, go out and have fun and display your sense of humour, the girls that react well to it, qualify to what you want, what ever you want, screen for it and if she doesn't have it, don't waste your time on girls you don't want, just because you like the way she looks, if you are seeking anything beyond just sex, then you will find no matter how good looking she is, it just won't feel right

and if you are just only looking for good looks and sex, you can really simply just screen for that, and get to the point of what you want, screen for mutual interest with what you want, qualify them on WHAT YOU WANT, show your intentions and act on them

screening is important and it is not a means to just get someone to like you, screen for yourself, not for her, and when I say screening I don't mean just interview girls and onto the next one, be very observant with what is going on, how is this girl responding, what is she like, you will develope your own game in time, but you should know that m3, is not the be all end all, it is not a perfect roadmap to a girls vagina, you will find it is a decent guide on how to meet people you don't know and make friends, if she is attracted to you and you escalate well, you can make that work for you, but if not, no amount of m3 can help you, seduction is not linear, you will end up friend zoned if she does not find you attractive, and it is not what you say that makes your attractive, it is not attraction routines, it is simply who you are

make an effort to actually connect with the girl you are talking to and screen if she is really a good match for you, beyond just... yah I like her pretty hair, she has a nice ass, I want her, find out if there is a connection between the two of you, if you get along, if you share interests, if she is cool

focus on the connection, more then analyzing what you are doing while in the set, analyze after and just practise
