However, I also have noticed that there is a lot of biases around when beginners and intermediates tries to assess whether a girl is a waste of time or not. Maybe she is a bit cold and grumpy. You assume she is hard? but what if, once you crack the initial phase, she ends up having pristine logistics and no resistance to sex. Was she hard?
Or maybe she is hard, but you have perfect logistics and perfect setting to run the type of game that is required to "crack her".
Many examples here. This is why I think going for the early game screening thing as a default, may not be so wise after all - at last not all the times. It can easily turn into a cope/crutch.
