I have only just started getting into daygame but i can tell you already dude its best to get their number AND arrange a meetup while you are still talking to them an iinstant date would be even better however those are difficult and i have yet to go on instant dates from daygame cold approach.
If you are only going for N closes all the time you are letting these girls become too important to you. Always push further if you are getting IOIs and let go of the outcome
Hope all goes well
PS sorry i didnt include anything on text game. I suck shit at text game
