Very simple truth, you're not a rockstar - insofar, you're not famous, so of course you aren't priority 1 in her life, even if she's feeling you. We all know its bullshyt, with how much people check their phones, a bytch can't text back within 30 mins? Its never that she "can't". She's simply not interested in chatting with you, unless you have something planned. Even girls who treated me like a living god, took long to reply. Women are vapid, they're not with any kind of real conversation that doesn't involve you punching their throats with your cock. So you have to act accordingly.
This of course is no different to emails, AIM, and screening phone calls. Its been done in its own context for decades. The goal is to try to skip texting or expedite the process and meet up with the broad. I like your bravado OP, but you're trying to reinvent the wheel, we already know the text game, all women do it. So the gist of your post should really be; Chase it if you want to, I prefer not to text at all and meet up.
