Ribs and chicken are killers if they cook too fast. I would agree with taking them out and then letting them finish so they come off at the correct time, if you get in a pinch. The best thing you can do is just practice more (who doesn't love ribs!) so you can get more consistent with the times and temps. Best of luck!
