I disagree with that conclusion mind. The delta is the MAX speed they can go. And under VSC there could still be that intention to be right on that delta the whole time so you don't give time away.A red flag and VSC have the same delta times, this was discussed with Bernie so it was ok for VSC and not a red flag as was already on the final lap
Red flag is more "crawl if you like, the race doesn't currently exist. Just don't go faster than X".
