You should not be able to make a stop that counts toward that minimum while laps are not counting.

I found it interesting that they did not count laps after a red until the green came back out. I forget who was leading, but they had not made a stop and had a lap on the field; pitted under the yellow after red with laps not counting... counted as his stop and he kept a lap on the field instead of it cycling back around. Free lap. Some how they still figured out how to lose the race though. Really grabbed defeat out of the jaws of victory.
