You confirming with her is seeking validation and approval. A no no. It shows that you are unsure of yourself and her. Never a good sign
Your thinking or worrying about how confirming a date appears to her at the day of your date is seeking validation and approval and shows that you are unsure of yourself.
Men and women with significant options know how this game works. You or she may have a handful of dates scheduled, some will rain-check, others will naturally drop off, and a couple you may meet. It's entirely normal within the sphere of men and women with a plethora of options to confirm a date. I can made a date today for tomorrow, and then tomorrow decide otherwise or even forget (see story below), and if I don't reach out to her and she to me, then the date is not on.
Although some women will reach out to you to confirm, some women in NYC (especially Eastern European types) are more traditional-minded and expect the guy to lead, so if you don't confirm and she doesn't confirm for this reason, then you have no date. Seems jejune and entirely inefficient.
What's worse (as I saw proposed in this thread) is showing up to a date (getting ready, and driving there) without confirming and she doesn't show because no one confirmed. This happened to me once, where neither her or I confirmed, and the girl actually showed up to the date, LOL. She texted me from the place, "I'm here." I literally forgot about her and didn't even know who she was until I scrolled our text conversation. I'm not kidding.
Though, as you are progressing, you must have structure (rules), irregardless of how efficient that structure is. At the epitome of "game," you surrender structure for fluidity and do what serves you best.
The only exception to the above is when you are 2x -10x scheduling for one night, and your best option texts you to confirm, and you have no desire to meet the others and so you let them drop off. However, even here, if you want to most efficiently raincheck the others to keep them in your pipeline, you should initiate the rain-check.
