Lots of opinions about this.
What I do
1. Schedule only 48hrs out at most (maybe 72 maybbbeee bit too long imo).
2. Anything else soft schedule/suggest
3. Minimum of chatter
4. Day of, usually they text first. Reassure.
4a. Probably okay to text first if super close to meetup time. But usually they do.
4b. The mindset of being out whether or not she comes/even if she stands you up, is a good mindset.
You're off my preferred script. I would definitely wait. Go talk to a few more girls in the interim. Too much focus on just this one, not a strong position.
