The original question was asking how much time would be allowed to drive after the 7 hour sleeper break. Yes a 10 resets the clocks but that is confusing the question here. If the driver used 5.5 hours of drive time prior to the 7 hour sleeper break, they would have 5.5 hours remaining to drive afterward, minus 14 hour limitations.
You take the drive time you used prior to taking the 7, the subtract it from 11, and that's what it leaves you. When you park for 3, you take the drive time you used from the time you ended your 7 and subtract from 11. The idea is to not use up all your drive time.
