Exactly. My hourly rate is massive. But I only get paid for the actual hours that I work. So if I only work 4 hrs one week, I only get paid for those hours.
And if I'm in court for ten mins or for the whole day, my rate is the same. And that rate includes preparation etc.

I never get paid for the admin/billing/phone calls/research/etc that I do. That's all off my own bat, so to speak.
For example, it's Saturday afternoon and I've spent three hours reading the latest case law. That's not paid. I do that 3-4 times per week. That's 9-12 hrs of unpaid work each week.

TBH I have absolutely no idea what my "rate" would be if I added in all the unpaid hours. And the schmoozing. Don't forget the schmoozing. I reckon it costs me $200/wk for schmoozing. But you have to spend money to make money in my game... that schmoozing gets me work.
