We still don't know for sure if there's any NEL penalty this season. I think the odds are that K/V will get the 30 minute penalty for not being on the required flight, they won't have any "time saved" added to that penalty since they didn't save any time.
I suspect they will be hit with a NEL penalty of some sort; if not that means WRP has abandoned the NEL penalty this season.
Well this is a TBC leg, just like Sydney. Jet and Cord were not penalized for checking in at the Sydney faux pit stop last, so I'm inclined think that this one works the same way and Kent and Vyxsin will not be penalized either. I think they might have just replaced NELs with TBC legs for this season to make it harder.
As was discussed during the first two episodes, these really cannot be called TBC legs; there have been instances in the past where TPTB had teams complete a leg, then within the same episode had teams start the next leg. The use of "TBC" now can't be used as a determinant of whether there is a leg, or an uberleg. The mandatory rest periods no longer have a standard length, and now, we can see that the length can be zero. With that, we have to look at the teams' arrival at the mat. If there is a greeter with Phil, then there is a leg; if there isn't and Phil tells a team to keep racing, then we've got a an uberleg.
(Some people call what I call an uberleg, a TBC leg. With the developments in this edition of the no rest period pit stop, I think I got it right in TAR 6 when I coined the "uberleg" as I've never adopted the "TBC" leg terminology.)
As to the NEL terminology, there were no NEL penalties the first four seasons, so I don't see a need to change the terminology. The only difference from those early seasons NELs is the no rest period pit stops.
