Congrats on the close, man. And good job writing a report about it!
Just have a few comments on this section:
These things you listed are all tools you can use to improve your day 1s and day 2s with girls you're really into. In this situation, it was pretty obvious the girl was keen and making things easy for you, so it probably wasn't necessary to do those things to get the close.
Ideally, you want to use qualification and future projection on girls you really like and want to see again (or on girls who are objectively hot, because they're being pursued so often so you need to set yourself apart). I'm not sure how interested you are in this girl, but since you gave her a 6 rating, I'm guessing you're not that into her? Can't really tell.
IF you did want to see her again or keep her as a regular, it could have been a good idea to suggest a second date, do some future projection or just spend more time with her in general before pushing for a close.
It's important to remember that future projection, bounce seeds, qualification, getting info about dating / sex experience, etc. are all just tools you can use to progress a pickup. You don't have to (and won't have to) use them for every single set. Things aren't so rigid. The individual girl and individual scenario will give you a sense of what needs to be done.
A big part of being good at pickup is being able to look at any given situation and understand what tools are best for handling that specific situation and then be able to deploy them properly.
Keep writing FRs! And remember: you learn more from the FRs where you fail than from the LRs where you close
Congrats again, man. Looking forward to seeing more of these from you!
