I'm starting to get closer and closer to being ready for my first real serious night of practising approaches in bars after several weeks of inner game and newbie mission stuff as well as reading a lot of stuff here (according to my current plans I will probably start next weekend).

But I have 3 crucial questions that need to be answered before I can feel certain enough to go through with this!

1. When is it ok to go to a new set immediately after finishing with one? Like all newbies, I think approaching several sets a night is a good way to get loads of practise early on in my PUA career. But if I SOI and PP etc a lot and in a very convincing honest-sounding manner, it would probably not be a good idea if the target from the previous set that I just K closed is still watching. Obviously if I fail at a set it's ok to move to a new one immediately. Same if I got a "rejection by #-close". But what about other cases, say after a K close? Now, assuming I closed this HB and I leave her table, it would seem odd to proceed with a new set immediately. Should I move from the successfully closed set to sit down with some friends for a while, then open a new set after I've seen the closed one leave? But if the closed one refuses to leave and hours pass... This whole situation could develop in many embarrassing ways, I think, so I'm wondering what routines and rules people here have for such scenarios? I.e., some sharp, precise definition of drawing a line here, to allow me to act decisively and in a way I've thought through properly beforehand? Also, is it ok to move back to a target I already closed earlier in the evening, or is that doomed to lead to total failure?

2. I'm curious about how to generally behave with closing. Should I go for an easy close with a set and then leave, or should I stay in the same set and always push towards F close if I think I have the option?

3. If I would ever find myself forced to end conversation with a set I have opened, because I got panic or realized, from a closer distance, that they're either too difficult or simply people that are annoying in a way that makes it difficult to keep a smile at them (I still have some inner game trauma stuff popping up occasionally making it difficult to smile to some people), how would I do this? An improvised # close and then go to a new set? Like:
"It was nice talking to you, perhaps I will call you" *gets her number* *goes away* "See you guys" *smiling* Would this be a good ending that allows me to proceed to a new set immediately afterwards?

If you just got the K-Close, why eject for another set? I say keep in there and go for the F-close, or a time bridge if the logistics are wrong that night. When you get into deep comfort with a girl it is not the right moment for a jealousy plotline, she'll just decide you're a player and flake for sure.
In general it's bad to leave right after you take the number, it gives the impression that you've gotten your prize and off you go. Again, high flake probability.
Don't feel bad about just ejecting from a set that you're not feeling or otherwise isn't going well. #-closing anyone that you've no intention of calling is a waste of time, and is really a symptom of seeking validation. A good ending would be: " I gonna go over there, nice to meet you guys!" and out.

Ok, thanks for the advice, sounds very reasonable! (will look up timebridge more in detail, I think I know roughly what it means though)

About F close, I have a problem in that I live with my parents SPAM, so I can't invite her home to me. How would I F close (phrases etc) in such a situation? Basically ask if we can go to her place?
