Didn’t watch the video but I have a certain way I track or categorize numbers.
If she was receptive and warm to me when I got her number she goes into Category 1.
If she gave me her number but I feel it’s a low chance of getting her out on a date she goes into Category 2.
I have a different way for dealing with each category. Essentially I use my standard text game on 1 and try to quickly establish just enough rapport to get them back out to see me in person.
For 2, I don’t use the word date. Instead I invite them out to hang with my friends when we do fun social stuff and I encourage them to bring a friend of either sex.
My buddies do the same and our social circle is always filled with cool new people and often the girl with being a female friend along with her. While the original girl may have not been very receptive for whatever reason, sometimes their friend is!
This method, if you have buddies who do the same, keeps a constant influx of new people coming into your circle and if you set yourself up as the leader of the circle you get even more benefits
