Then NASCAR should've emphasized that specifically.
My point still stands that the rule is an unorganized, vague mess. If they don't want intentional cautions to manipulate the outcome of a race, then just say it. State specifically what is and is not breaking the 100% rule. Otherwise teams will start exploiting loopholes like Martinsville pit road.
And that's an easy fix. Make a minimum speed on pit road under caution. If you drop below that minimum average in one of the timing zones, you get a penalty. With this the only reason you'd be under it is if you have a major issue and then penalty doesn't matter anyway. You get in, make your pit stop, get out. No games.
Or a slightly more extreme alternative: go back to single-file restarts exclusively for Martinsville (and maybe Bristol but that's not the topic at hand).
