So I read the whole paragraph, and I'll say my previous statement seems valid. In subpart (A)(4) 8 for one pilot in any 24 consecutive hours, or (5) 8 for 2 pilots between required rest periods.

So I'd say No, you cannot accept more than 8 hrs of flight time per given rest period(and of course how you fly the 8 is whether you're single or two crewed)

If you hit 8hrs up to 9, you have to get 10hrs of rest. This as I mentioned above is for unforeseen circumstances only that your flight times were longer than predicted.

Now usually the calculated flight times aren't the problem, it's usually your duty day that becomes an issue for at least the unscheduled guys. Your freight/pax are late, weather holds you on the ground longer, etc.. If you're going to knowingly fly out of your duty period, that's a big no-no! Flying over 8 is harder to do, because the planning software etc.. today is good enough to hit times within .1 over a whole night(at least for my profiles).

I don't have any experience with reduced rest operations, I'm going to defer that one to someone who has.
