For those who do not know where the scoreboard is, here is the link:
https://www.nar.org/nrc-scoreboard/
There's no "Z" division. There's A,B, C, and now "D" for Teams.
I do not see "Z" listed on the scoreboard now, I guess that someone typed in the wrong thing. The results are also sent to the Contest Board representative for the region the contest was held in, to check and verify the results. So what you saw likely was before the CB reviewed and approved (fixed) the results.
Last Saturday, I was CD where a few National Rocketry Competition (NRC) flights were made during a club launch. Jay King (C Div) had a great 2-flight total in A Streamer Duration. 1:55 for flight 1, and 4:25 for flight two (a really nice thermal). That's a total of over 6 minutes, which locks Jay in for top ranking in that event since 6 minutes is the NRC "max" total for A SD (scoreboard software will get tweaked to display the max times.
Currently in C Div there are four flights over 6 minutes (360 sec) in 1/2A Parachute, which means that those 4 are tied for 1st place NRC ranking in that event.
I will have an interesting announcement in a few days related to NAR contests. Not ready yet though.
