Option A sees the NXT Arrival infobox be the first event to use the new parameter and have it be the link in the chronology back to the pre-WWE Network days. Though this would include putting Extreme Rules (2014) in the new parameter even though it was not a WWE Network event, and we would note this by putting "PPV Only" underneath it's link, as shown. It would most likely be the only time this would ever be done. Extreme Rules (2014) itself, of course, would still only use the old fashioned PPV chronology parameters and would still link directly to WrestleMania XXX.
Option B sees WrestleMania XXX as the epoch instead. The WrestleMania XXX infobox would do all the work and use the PPV parameters one last time for an infobox link back to the pre-WWE Network even of Elimination Chamber (2014), but also use the new WWE Network parameter to link back to NXT Arrival, as it should. In this option, as with Option A, the Elimination Chamber (2014) infobox would remain unchanged.
