In sailing, my favorite is when people hit the mark (and know it). If you're DFL with no chance of passing anyone, I'd say keep going so you don't hold up the next start. Otherwise, do your turns and sleep better at night.

Nah, do your turn it's what 15 seconds to do the turn? The fleet can wait and there will always be someone that will make an issue of it and/or remember it later. Run clean all the time no exceptions.
