Fundamentally flawed question and I'll explain why. Social calibration is an individual process that you must undergo by field testing the theoretical concepts you learn about on the internet and asking yourself what goal you want to achieve with complete honesty. My game will not work for the next person and theirs for me. This goes for everyone reading this: stop asking people on the internet to make decisions for you. Go out, fuck up, reflect, and calibrate. That's the process.
When you deal with girls, there are two mindsets you can have: abundance or scarcity. I'll break down what actual abundance is and not the youtube filler word that people trout out to hit your dopamine receptors. Actual abundance has little to do with the number of girls you're sleeping with.
Abundance is a three step definition:
1) liking yourself
2) knowing you have value to offer
3) knowing there is ALWAYS someone out there who will value you and you can connect with
Operating from that basis, your question turns into what you are willing to do to get laid. If you like the girl, sure, drive halfway and have a good date. Having a fun date usually has a high chance of seeing the girl again and maybe hopefully doing something hot with her like destroying her cervix.
What you shouldn't do is make decisions out of fear AKA scarcity, which is exactly what you're doing by trying to read her mind and figure out why a girl on OLD flakes on you (hahahaha, better off solving world hunger).
I'll end by sharing what I do. Disclaimer here: you are an absolute idiot if you blindly do exactly what I do after everything else I wrote in this post. When I was in my ho-phase, I made girls come to me. It's another form of screening because if she puts up resistance towards it, then I'm not going to give her my time when I know another girl would come to me. 99% of the time, girls who are genuinely interested are not going to stop responding because of the location you pick; at the very least, they'll say they want to meet somewhere else.
